Bidens best attribute right now is that trumps a terrible candidate, if trump wasn't the alternative I wouldn't give him a chance at reelection.
You put anyone else besides Trump up and the L gets even worse for the GOP
Trump is literally keeping the party galvanized and energized to vote
The policy positions of the GOP are why they are losing more than candidate choice
They have gone all in on the evangelical/culture war sect of the party which forces them into unpopular election positions and ultimately losing campaigns
Desantis and Youngkin going from GOP darlings to no shot in their home states is evidence of how the house of cards is tumbling down
Gov't Shutdown on the GOPs watch might be the final nail in the coffin for them not even trump getting indicted
