Though the presidential election is barreling toward its end, the “axis of furious conservative activists and hard-right media that spawned Trump’s nationalist and conspiratorial campaign is determined to complete its hostile takeover of the GOP, win or lose,” writes The Washington Post’s Robert Costa. According to Costa, conservative media figures like Breitbart News’ Stephen Bannon, InfoWars’ Alex Jones, and Fox News’ Sean Hannity have spawned a “grievance movement” seeking “to claim the [GOP’s] future as its own,” whose likely “first post-election target” will be House Speaker Paul Ryan (R-WI).

Trump and far-right media have been in lockstep throughout his presidential campaign: Bannon, the former head of Breitbart News, is Trump’s campaign chairman; Jones, a 9/11 truther who leads the conspiracy website InfoWars, feeds Trump conspiracy theories for campaign speeches; and Hannity, the far-right prime-time pundit on Fox, has gone to all lengths possible to defend and praise Trump. Trump’s engagement with hard-right, conspiratorial media figures has elevated and mainstreamed them, offering them a platform that has long been out of reach.

On October 20, Costa reported in the Post that “the fringes of the GOP [are] now managing the Republican nominee” and that the party’s “Donald Trump-driven divisions will not cease on election night.” Costa wrote that the conservative media network -- which has seen “high-minded journals and Fox News … supplanted by a galaxy of websites such as Infowars” -- “stands ready to claim the party’s future as its own,” setting the stage for an intra-party showdown “that will haunt Republicans for months and years to come.” From the October 20 Washington Post article:

The first post-election target for the grievance movement is likely to be House Speaker Paul D. Ryan (R-Wis.), who has drawn Trump’s wrath for not supporting him more fully. Trump’s backers, both inside the House Republican caucus and out, are already talking about a takedown.

Fox News host and Trump ally Sean Hannity said in an interview after the debate that Ryan was a “saboteur” and “needed to be called out and replaced.” Hannity said he would actively urge hard-line conservatives to launch bids against Ryan.

At the fore of this conglomeration is Stephen K. Bannon, the former head of Breitbart who has become Trump’s most influential confidant. Bannon encouraged the candidate’s claims of voter fraud and references to a deeply corrupt global conspiracy of international banks and corporate-friendly politicians.

Bannon has been a prominent backer of political assaults against Ryan and other Republican leaders over the past decade from the party’s fringes — boosting primary challengers against Ryan and others, and warning against compromise on hot-button issues such as immigration. But with the fringes of the GOP now managing the Republican nominee, a retreat is far from likely.

Bannon’s friends say that he has become emboldened during his time with Trump, and that they expect him to work with his network of allies, super PACs and websites to battle Ryan and the Republican establishment throughout 2017 as that wing of the party tries to rebuild the GOP brand.

It is not just Breitbart that stands ready to claim the party’s future as its own. The conservative media, once dominated by high-minded journals and Fox News, has been supplanted by a galaxy of websites such as Infowars, which is led by Alex Jones, who calls the 9/11 terrorists attacks an inside job.

Articles on those outlets have found their way into Trump’s speeches and been spread widely across platforms such as Facebook and Twitter, often building into a frenzy that leaves traditional GOP messengers unable to shape the consensus within their own party.
