In the 72 hours since Donald Trump won the White House, the president-elect has struck an atypical tone of unity, reaching out both across the aisle and to a number of Republican leaders who, in the past, offered tepid support if not active opposition. But while the shift in rhetoric has assuaged some fears of the intra-party civil war that threatened to sunder the Party of Lincoln earlier this year, a now emboldened faction within Trumpworld is signaling just that, reportedly hatching plans to exact revenge against G.O.P. squishes—and Paul Ryan might be at the top of their blacklist.

After holding onto the House of Representatives and the Senate, Trump’s victory represents the best opportunity in years for Republicans to enact an unrestrained conservative agenda. Many within the party reportedly hope that Trump—a Beltway neophyte who never showed an interest in matters of policy on the campaign trail—will hand the reins to his more seasoned peers, specifically Ryan. “Donald Trump and policy-making don't really belong in the same sentence,” one Iowa Republican told Politico. “Paul Ryan will make policy and Donald Trump can Make America Great Again,” they added. The Speaker of the House has already drafted a far-reaching budget ready to be rubber-stamped by the president-elect when he takes office. Ryan plans to push the omnibus bill through Congress via the budget reconciliation process, which could essentially wipe out President Barack Obama’s legacy with a single party-line vote.

But G.O.P. leaders hoping that a vote for Trump was a vote for Ryan’s agenda should take pause. Ryan was notable among the Republican leaders who did not embrace the former reality-TV star’s ascension to the top of the party ticket, and only reluctantly offered Trump his conditional support. As a result, the Wisconsin congressman has a target on his back. Breitbart News, whose former executive helped run Trump’s campaign and is now being considered for White House chief of staff, has reportedly pledged retribution for Ryan’s waffling support. “Ryan will not get amnesty for his actions against the conservative movement and the American people,” a source close to Breitbart told The Hill on Wednesday. According to an internal Breitbart e-mail from December of last year, which was obtained by The Hill, Bannon wrote that the “long game is [Ryan] gone by spring.” In the final weeks of his campaign, Trump was openly attacking the politician on Twitter. “Paul Ryan should spend more time on balancing the budget, jobs and illegal immigration and not waste his time fighting the Republican nominee,” Trump tweeted. Now, with Breitbart effectively weaponized as the media arm of the Trump White House, Ryan could soon find his grip on the Speakership more tenuous than ever.

If the soon-to-be commander in chief and his entourage of loyal apparatchiks do seek vengeance, Ryan certainly won’t be the only politician they go after. “It’s one thing not to have been for him or to have had a disagreement, but if you went out of your way to be an asshole, then we’re not going to helpful,” an anonymous source close to Trump told Politico. Omarosa Manigault, a former Apprentice contestant and vocal Trump surrogate, told the Independent Journal Review on Tuesday night after Hillary Clinton’s defeat, “It’s so great our enemies are making themselves clear so that when we get into the White House, we know where we stand ... Mr. Trump has a long memory and we are keeping a list.” Another source expressed resentment after having been “scorned” for supporting Trump, adding, “We were told this would be a black mark on our careers we couldn’t come back from." (Campaign spokesperson Jason Miller dismissed the idea that the president-elect will pursue a vendetta now that he has been elected, telling Politico, “None of this is true.” Another campaign source also brushed off the idea: “There is not and never will be a blacklist. Trump is focused on talent like any C.E.O. The swamp games won't apply in his administration.”)

Even if Trump’s inner circle does not intend to launch a crusade against those that were critical of the president-elect, one of the largest super-PACs to back the billionaire during his historic presidential bid does. The Great America PAC, which spent at least $30 million to get Trump elected, plans to continue its efforts to support Trump in the wake of his election—even if that means going after high-ranking members of the G.O.P., The Washington Post reports “Suppose there's a battle between him and [Speaker Paul] Ryan or someone else,” Ed Rollins, the super-PAC’s senior strategist, told the Post. “We can go out there and do what’s in the best interest of Trump.”
