Biden is incredibly weak, yet no elected Republican leader is picking a fight with him. The GOP, party of the eternally dry powder. Mitch? Kevin? Are you guys even alive?
It is obvious that the establishment GOP is in on the whole thing. They made a deal with the Democrats to cheat Trump out of his second term through election fraud so that the status quo could be returned to. The whole deal with Mike Pence turning traitor on Jan 6 makes sense now. Trump knew exactly what Pence was going to do but wanted his supporters there with him nevertheless for one last hurrah.
I doubt that even Trump knew what would happen at the Capitol. I don't think he expected that Capitol police would just step aside and let a bunch of supporters walk right in to create a "Reichstag Fire" incident (led by a small group of leftist activists who were in on the scheme). Trump likely envisioned having a few hundred thousand of his core supporters making a lot of noise outside just to show the coup plotters that we were on to their game.
So no, I don't think the establishment Republicans are going to put up any kind of fight over the next year and a half. It's up to us to primary as many of these rascals out as possible and put in MAGA candidates for the 2022 mid-terms.
