Some people are easily amused...
Did you have a substantive reply? How is looking at the current situation and thinking that someone making predictions of electability in a general election this far out, in light of recent history is being easily amused. There’s a number of intervening events that could drastically skew that, and thinking that those candidates won’t look at it the same way is laughable to me. In essence, they’d be saying I would have been better than, and one of two Democrats that could have beaten Trump in a general election, but I’m not the best Democrat for the job if he’s not running against me. I just don’t see that out of them.
I think it’s highly likely Trump will be impeached, I also think it’s pretty unlikely that he will be convicted with it 67 votes in the Senate. But I would not be willing to wager more than the cost of a six pack of beer on any of those outcomes.
So that leaves him in office, and dealing with whatever political fallout there is from the process, but knowing him, he’ll draw as much blood (or at least try to for appearances) from any of his potential opponents as he can. Who knows what skeletons could come out for him or them that could linger into elections.
