This thing isn't final yet, but if it goes the way I think it's going, this was a good day for traditional non Trump slurping Republicans/Conservatives.
IF it happens like I'm seeing it, Biden is going to win a thin electoral victory, the Republicans will hold the Senate, and pick up seats in the House. The Republicans did absolutely fantastic in competitive house districts. They won a bunch of Senate contests, many comfortably, that dems thought were vulnerable and poured TONS of money into. The Republicans made great inroads with minority voters, especially Hispanics.
Basically, Republicans everywhere ran ahead of Trump. Trump the person was rejected, as he should have been, but this has been a very telling blow to the "resistance" direction of the Democratic party. They were very smart/fortunate to have nominated the "boring moderate" despite best efforts, or they'd have likely lost clearly to Trump again.
I don't expect any attempts by Trump to legally challenge anything to get any real traction. Despite what people want to claim, while judges might be liberal or conservative they're rarely purely partisan, and I've yet to see a compelling legal challenge to be made. We'll see. Plus, I'm pretty sure that most Republican power brokers look at this income the way I do...very, very encouraging for the future.
