People won't be voting for Republicans, they'll be voting against Democrats. They'll be voting against lockdowns, the destruction of small business, wearing the goddamn face masks, war with Russia and being constantly told they're bunch of hillbilly white nationalist fascists. I mean, personally it LOVE it when somebody takes the time to point out my white privilege and what an awful person I am for not keeping it foremost in my mind at all times.
Of course, Republicans will try and take credit for their upcoming landslide and act as though people are enthusiastic about their agenda and actually like them and their embarrassing interest groups, but that would be disingenuous. The simple truth will be that they are not Democrats.
The Democrats for their part will blame their defeat on the fact that so much of the country has become white nationalist fascists who don't listen when you tell them about their white privilege and what terrible people they are. That, and the fact that their Republican opponents were all aided by Russian agents and hackers.
