The GOP’s escalating infighting over immigration now has a pair of PACs lining up millions of dollars on opposing sides of Republican primaries across the country.

The dueling pledges turn a congressional fight over Rep. Maria Elvira Salazar’s (R-Fla.) Dignity Act into an electoral proxy war between hardliners and moderates over how far the Republican Party should go on immigration reform. It’s putting the bill’s 20 House GOP co-sponsors in the spotlight.

The Homeland PAC, backed by immigration-restrictionist Republicans, launched last week in an effort to primary some of those co-sponsors. Meanwhile, American Business Immigration Coalition Action, a pro-immigration group, secured $1.2 million to protect them through its Building America’s Economy PAC and hopes to raise $5 million in total, according to plans first shared with Blue Light News.

The Dignity Act, a bipartisan bill, has faced an onslaught of criticism from conservative MAGA influencers and allies of President Donald Trump, who view it as a nonstarter. While the bill doesn’t create pathways to citizenship, it would allow millions of unauthorized immigrants to eventually gain work permits and remain in the U.S. legally.

Republicans like battleground Reps. Gabe Evans (Colo.) and Brian Fitzpatrick (Pa.) have signed onto the bill. But critics pan it as “amnesty” and signal that the future of the Republican Party hinges on this debate.

“Donald Trump is not going to be around forever,” said Ryan Girdusky, the GOP strategist behind Homeland PAC. “The goal is to focus and to put our efforts into the future, and make sure Republicans know that the demand for stronger borders and for reforms to legal immigration and illegal immigration means something. We are not going to roll over and go back to business as usual.”

The clash is playing out as the White House recalibrates its own message on immigration amid plummeting public perception. The administration has shifted away from using the phrase “mass deportations” in public messaging and says it is focusing on deporting the “worst of the worst.”

“Extreme-right internet influencers have escalated their attacks, and we want to ensure the leadership on commonsense immigration reform are protected,” said Rebbeca Shi, CEO of ABIC Action, whose PAC is seeking to defend Republican co-sponsors of the Dignity Act.

Salazar has defended her bill, saying it offers workers “dignity.” But former Trump adviser Steve Bannon called it the “screw American workers” bill. Conservative pundit Megyn Kelly said the bill “is not going to go over well with the GOP base, with the America Firsters.” And conservative members of Congress, including Sen. Mike Lee (R-Utah) and Rep. Brandon Gill (R-Texas), slammed the bill as a betrayal to Trump’s base.

Girdusky, whose Homeland PAC is dedicated to “ending the career of every Republican who supports amnesty and sells out the American people on immigration,” won’t reveal which specific lawmakers he’s targeting or how much money he plans to spend. Several of the Dignity Act’s cosponsors are retiring or represent competitive districts, but Girdusky said his group will focus on those in safe-red seats with primary challenges.

“If any of these members have a change of heart and say, ‘Wow, this is actually a terrible bill for American workers and for the border and enriches human traffickers, I’m going to drop my support of it,’ I’m not going to challenge them in a primary,” he said.

Several hardline immigration groups have jockeyed for influence with the Trump administration, hoping to convince the president to keep his promise to enact the largest deportation initiative in history. But leaning into such an approach risks turning off voters, many of whom disapprove of the president’s handling of immigration so far.

New results from The POLITICO Poll shows that Americans’ views of Trump’s deportation campaign remain broadly negative in the three months since its enforcement surge in Minneapolis. Half of Americans, including one quarter of Trump’s 2024 voters, said his deportation campaign is too aggressive.

Shi said her group will defend the Dignity Act’s cosponsors — both Republicans and Democrats — in primaries, as well as Republicans who voted to reinstate temporary protected status for Haitians last week. She believes signing off on a bipartisan immigration reform bill like the Dignity Act would be a smart political move for the White House ahead of the midterms.

“The White House is very sensitive to the polling on this, and the numbers haven’t changed since Minneapolis,” Shi said. “That’s why the next logical step to win in November is to actually have solutions.”
