From Paul Findley to Thomas Massie: How the Israel Lobby Purges Republican Dissenters

Thomas Massie’s defeat marks the most expensive House primary in American history.

Rep. Thomas Massie’s (R-KY) defeat on May 19, 2026 represents the latest chapter in a decades-long campaign by the Israel lobby to eliminate Republican dissenters from Congress. Thomas Massie, the libertarian Republican from Kentucky who represented his district for seven terms, lost his May 19, 2026 primary to the Donald Trump-backed challenger Ed Gallrein by a margin of 54 to 45 percent.

The race shattered records, surpassing $35 million in total spending per FEC data and becoming the most expensive House primary in American history, according to ad tracking firm AdImpact. Super PACs backing Gallrein poured more than $16.4 million into defeating Massie—compared to roughly $10.1 million that independent groups spent supporting him—with pro-Israel organizations and donors accounting for the dominant share of anti-Massie outside spending.

Massie’s ouster was not an isolated event. It represents the latest and most expensive example of a pattern that has persisted since the 1970s. The Israel lobby, led primarily by the American Israel Public Affairs Committee (AIPAC) and its affiliated political action committees, has systematically targeted Republican members of Congress who deviate from unconditional pro Israel foreign policy positions. The record is clear. When a Republican votes against Israeli aid, meets with Palestinian leaders, backs Arab arms sales, or calls for evenhandedness, AIPAC responds with coordinated donor networks, PAC money, and media campaigns to fund their challenger.

The Case of Paul Findley

Paul Findley served as a Republican representative from Illinois for 22 years. He was a co-author of the 1973 War Powers Act and an outspoken advocate for engaging with the Palestine Liberation Organization. He met multiple times with PLO chairman Yasser Arafat, famously calling himself “Arafat’s best friend in Congress.” He demanded the suspension of U.S. military aid to Israel on grounds that Israel was using American weapons in violation of U.S. law during its 1982 invasion of Lebanon.

AIPAC declared Findley its “number one enemy” and his campaign the “principal target of Israel’s lobby” in the early 1980s. The organization coordinated pro-Israel PAC fundraising for his Democratic opponent, Dick Durbin—now the senior senator from Illinois. AIPAC raised over 80 percent of Durbin’s $750,000 in campaign funds from around the country, defeating Findley by fewer than 1,500 votes. As Findley later wrote: “In 1982, when AIPAC claimed credit for keeping me from election to a 12th term in the House of Representatives, I became the lobby’s prize trophy.”

The Political Execution of Pete McCloskey

Pete McCloskey was a decorated Marine combat veteran who represented San Mateo County, California as a Republican from 1967 to 1983. He was the first Republican to call for Nixon’s impeachment and a leading anti-Vietnam War voice in the GOP. In 1982, McCloskey ran for an open U.S. Senate seat in California.

His campaign was damaged by his call to slash aid to Israel unless it gave up its territorial claims in Gaza and the West Bank. He lost the Republican primary to future governor Pete Wilson and acknowledged his controversial positions on Israel were a contributing factor in his defeat, per The Los Angeles Times.

Charles Percy: The Illinois Senator Who Refused AIPAC’s Loyalty Oath

Charles Percy served as a Republican U.S. senator from Illinois from 1967 to 1985, rising to become Chairman of the Senate Foreign Relations Committee. In 1975, Percy declined to sign the AIPAC-sponsored “Letter of 76” protesting President Ford’s threatened “reassessment” of United States-Israel relations. In 1981, Percy voted for the Reagan administration’s sale of Boeing AWACS early warning radar planes to Saudi Arabia—a sale AIPAC had mounted its largest ever lobbying campaign to block. Percy had also publicly called PLO leader Yasser Arafat “more moderate” than other Palestinian resistance figures, clarifying he meant “relative moderate” only in contrast with George Habash’s Popular Front for the Liberation of Palestine (PFLP).

Then-AIPAC Executive Director Tom Dine coordinated a massive nationwide fundraising effort against Percy. California-based AIPAC donor Michael R. Goland personally spent $1.1 million on independent anti-Percy advertising in Illinois. Percy narrowly lost to Paul Simon by 50.1 to 49.9 percent. After the defeat, AIPAC’s Tom Dine delivered what became the most notorious boast in Israel lobby history: “All the Jews in America, from coast to coast, gathered to oust Percy. And the American politicians—those who hold public positions now, and those who aspire—got the message.”

The Fall of Roger Jepsen

Roger Jepsen served as a Republican senator from Iowa from 1979 to 1985. He was one of the most vocal opponents of the Reagan administration’s 1981 AWACS sale to Saudi Arabia, sponsoring a Senate resolution to disapprove the sale. In his own words, he had opposed the sale because “weakening Israel violated his religious conscience,” according to The Harvard Crimson.

But under White House pressure, Jepsen stunned the Senate by reversing his vote at the last minute in favor of the sale. The AWACS vote switch had been a major campaign issue in his 1984 race against Democrat Tom Harkin, who attacked Jepsen relentlessly for breaking his promise on the AWACS sale. Harkin defeated Jepsen in a landslide, winning by more than 150,000 votes.

The Million Dollar Hit on John Hostettler

John Hostettler represented Indiana’s 8th Congressional District for six terms from 1995 to 2007 as a staunchly paleoconservative, anti-interventionist Republican. After losing his seat in the 2006 Democratic wave, he attempted a comeback in the May 2024 Republican primary and was crushed by a coordinated, million-dollar campaign led by the Israel lobby. AIPAC labeled Hostettler “one of the most anti-Israel Republicans in Congress” during his time on Capitol Hill. He voted against virtually all foreign aid as a matter of principle, including aid to Israel. He was one of only six House Republicans to vote against the 2002 Authorization for Use of Military Force Against Iraq.

After leaving Congress, Hostettler self-published Nothing for the Nation: Who Got What Out of Iraq in 2008, arguing that a primary motivation for the Iraq War was protecting Israel, driven by neoconservative political appointees whom he identified by their Jewish backgrounds.

The United Democracy Project, AIPAC’s super PAC, spent approximately $1.57 million in attack ads against Hostettler—marking the first time UDP ever intervened in a Republican primary since AIPAC created it in 2021. The Republican Jewish Coalition Victory Fund spent an additional $955,000 supporting Hostettler’s opponent, State Senator Mark Messmer.

RJC CEO Matt Brooks announced the campaign with an explicit threat: “Let there be no doubt: if you stand against Israel, if you stand against the Jewish community, the Republican Jewish Coalition will work to defeat you.” Hostettler lost the May 7, 2024 primary decisively, with Messmer besting him by roughly 20 percentage points and going on to win the general election in the heavily Republican district.

The Takedown of Thomas Massie

Thomas Massie compiled a consistent record of opposition to Israel related legislation over fourteen years. He voted against every foreign aid package to Israel, consistently citing fiscal conservatism and opposition to all foreign aid. In 2021, he was the only member of the Republican caucus to vote against a standalone Iron Dome defense funding bill for Israel.

Days before his defeat, Massie introduced the “AIPAC Act,” legislation that would require AIPAC to register as a foreign agent under the Foreign Agents Registration Act. In the 2026 primary, the United Democracy Project spent more than $4.1 million against Massie, per FEC data. The RJC Victory Fund spent approximately $3.9 million. MAGA KY, a Trump-aligned super PAC managed by Trump aides Chris LaCivita and Tony Fabrizio and backed by pro-Israel billionaires including Paul Singer and Miriam Adelson’s Preserve America PAC, spent $7.5 million primarily on anti-Massie ads. Combined, the three PACs linked to pro-Israel donors spent more than $15.5 million in the race, per FEC data cited by Al Jazeera.

Massie stated throughout the campaign, “They’ve tried to buy my vote for 14 years, and it was never for sale.” After conceding, Massie remarked, “I would have come out sooner, but I had to call my opponent and concede, and it took a while to find Ed Gallrein in Tel Aviv.” He added, “For 14 years, those SOBs in Washington tried to buy my vote. They couldn’t buy it. Why did the race get so expensive? Because they decided to buy the seat, and it got really expensive for ‘em.”

AIPAC posted on X within minutes of the result, “Congratulations to US Navy SEAL Ed Gallrein for defeating anti-Israel incumbent Thomas Massie! Pro-Israel Americans are proud to back candidates who support a strong [US-Israel] alliance and help defeat those who work to undermine it. Being pro-Israel is good policy and good politics!”

The Percy Factor Lives On

Thomas Massie compiled a consistent record of opposition to Israel-related legislation over 14 years. He voted against every foreign aid package to Israel, consistently citing fiscal conservatism and opposition to all foreign aid. In 2021, he was the only Republican to vote against a standalone Iron Dome defense funding bill for Israel, joining eight progressive Democrats in a 420-9 vote.

In October 2023, Massie was the only Republican “no” vote on Speaker Mike Johnson’s pro-Israel resolution after the October 7 Hamas attack. He explained the resolution called for sanctions he opposed as a prelude to war, asserted foreign aid commitments he had voted against, contained “open-ended” military support language, and could broaden the conflict geographically. Days before his defeat, Massie introduced the “AIPAC Act,” legislation that would require AIPAC to register as a foreign agent under the Foreign Agents Registration Act.

In the 2026 primary, Trump-aligned groups poured more than $7 million into the race, while pro-Israel organizations contributed an additional $9 million to unseat Massie, according to the Washington Examiner. Massie stated throughout the campaign: “They’ve tried to buy my vote for 14 years, and it was never for sale.” After conceding, Massie remarked: “I would have come out sooner, but I had to call my opponent and concede, and it took a while to find Ed Gallrein in Tel Aviv.” He added: “For 14 years, those SOBs in Washington tried to buy my vote. They couldn’t buy it. Why did this — why did the race get so expensive? Because they decided to buy the seat.”

AIPAC posted on X within minutes of the result, calling Massie the “anti-Israel incumbent” and congratulating “US Navy SEAL Ed Gallrein for defeating anti-Israel incumbent Thomas Massie! Pro-Israel Americans are proud to back candidates who support a strong [US-Israel] alliance and help defeat those who work to undermine it. Being pro-Israel is good policy and good politics!”

Tom Dine’s boast after Percy’s 1984 defeat was not merely gloating. It was a deliberate message to every remaining member of Congress. Political scientists and former members have documented how the Percy and Findley defeats produced a “chilling effect” on congressional speech about Israel for decades. The Washington Post identified this as the “Percy Factor” in a 1986 analysis.

The same logic applied again in 2026, on a massively amplified financial scale. Massie explicitly acknowledged the deterrence logic: “If I lose on May 19, I’ll be out of Congress… The one whistleblower, if you will, in Congress, will be gone.” Kentucky’s Democratic Governor Andy Beshear, no political ally of Massie’s, stated: “Thomas Massie and I don’t agree on much. But billionaires and special interest groups don’t get to pick our leaders.”

The pattern from Findley to Percy to Hostettler to Massie remains consistent. Republicans who challenge unconditional support for Israel face coordinated, heavily funded campaigns to remove them from office.

The Generational Shift

Yet the Israel lobby’s grip on American politics may not endure. Polling data reveals a striking generational divide that portends significant challenges for pro Israel forces in the years ahead.

According to Pew Research, 41 percent of Republicans overall hold an unfavorable view of Israel. Among Republicans ages 18 to 49, that figure climbs to 57 percent unfavorable, up from 50 percent in 2025. Among Republicans 50 and older, approximately three in four maintain favorable views of Israel. The generational divide within the Republican Party has grown as pronounced as it is among Democrats.

A November 2025 Big Data Poll found only 29.1 percent of US voters side with Israel overall, declining from the 54 percent sympathy peak measured after October 7, 2023. Among young Republicans aged 18 to 29, the same poll revealed 33.4 percent prefer Palestine versus 27.9 percent supporting Israel, a historic reversal. And 52.9 percent of America First Republicans aged 18 to 29 now characterize Israel’s Gaza attacks as “genocide,” while only 29.2 percent reject the label.

A December 2025 IMEU and YouGov poll of Republican voters uncovered a striking Fox News variable. Netanyahu’s net approval among Republicans who regularly watch Fox News stands at plus 49. Among non-Fox News Republican viewers, that figure plummets to plus 11, a 38 point shift. Among Republicans under 45 who do not regularly watch Fox News, Netanyahu’s net approval falls to minus 8.

The same poll revealed significant policy implications from this shift. 51 percent of Republicans under 45 said they would prefer supporting candidates who would reduce US aid to Israel. 53 percent said the United States should not renew the annual aid commitment to Israel. 52 percent of Republicans overall and 59 percent of Republicans under 45 would prefer a primary nominee who prioritizes lower prices for Americans over funding Israel.

Just 23 percent of Republicans under 45 and 31 percent of Republicans overall prefer a nominee who supports unconditional funding for Israel. 48 percent of Republicans agreed that “legitimate criticism of Israel that should be protected under free speech is too often accused of being antisemitic,” while only 23 percent disagreed.

The Israel lobby can still muster tens of millions of dollars to unseat individual dissenters like Thomas Massie. But the demographic trends point in one direction. Younger Republicans increasingly reject unconditional support for Israel and favor candidates who prioritize American economic interests over foreign entanglements. As these voters age into the electorate and older, more reflexively pro-Israel cohorts pass from the scene, the lobby’s stranglehold on Republican foreign policy will loosen. For advocates of a restrained foreign policy free of Zionist influence, these trends augur well for the future.
