With so many of this year’s campaign battlegrounds located in suburban districts that are trending blue, it stands to reason that the Republicans who lose their seats Tuesday will be those whose constituents don’t demand absolute fealty to the president. The result, in this scenario, could be a smaller Republican caucus, yes—but one populated almost entirely by die-hard Trumpists.

As Trump has turned to culture war and conspiracy theories in the final weeks of the election, establishment groups like the National Republican Congressional Committee and the Congressional Leadership Fund have diligently amplified his message. In some alternative political dimension, these organizations might be laser-focused on the booming economy. Instead, they are running attack ads linking Democratic candidates to Colin Kaepernick, the black quarterback known for kneeling in protest during the national anthem, and warning darkly of a migrant caravan marching toward the border that’s allegedly full of criminals and gang members.

Helping to shape these narratives are populist right-wing websites like Breitbart News, which now play an important role in any Republican’s press strategy. Not long ago, one GOP strategist told me, it was common for candidates and lawmakers to assign specialized staffers to deal with these unseemly elements of the conservative media. They were to be appeased when necessary, but kept at arm’s length. Now, he said, they’re so influential and omnipresent that press secretaries are on the phone with them every day.
