Rep. Mike Johnson, the newly elected House speaker, has repeatedly flirted with what’s known as the “great replacement theory,” the idea that Democrats are scheming to supplant American voters with immigrants. The Louisiana Republican’s views show how fringe conspiracy theories have gone mainstream in the Republican Party at the highest levels of power.

On immigration, as well as on abortion and gay rights, Johnson’s elevation is a triumph for the far right. It has been widely noted that Johnson doesn’t come across as a MAGA bomb-thrower, despite his extreme views. That’s true on immigration, too: He voices high-minded platitudes about how providing asylum to the persecuted is a noble ideal, but he’s a big booster of the wildly radical House GOP border bill that would functionally gut asylum entirely.

That someone with these views now controls the House’s agenda bodes badly. Johnson has already declared that a top priority is fixing our “broken” border. Julián Castro, a former member of President Barack Obama’s Cabinet, anticipates Republican efforts to shut down the government to force Democrats to “remake the asylum system in the MAGA cult’s image.”

Congressional Republicans have long been split between establishment figures who favor compromise reforms (legalization of many undocumented immigrants in exchange for border security) and those who see migration as a wholly destructive force, an invasion to be rebuffed via mass deportations, an effective end to asylum and maximal border militarization. As Johnson’s new — and very powerful — leadership position reveals, the latter forces have decisively won.
