I'm still not sure Trump can win the general election at this point, which needs to be a top priority. Not above getting a placeholder candidate who might win (think back to Dole or even McCain), but high in the top five. Even if he does win, are we just looking at another four years of not being able to get anything done except executive orders that can be undone with the next president's signatures?
Trump has a lot of good points, and a lot of bad points, both to the political addicts and the man on the street. Will the balance out? Frankly, I'm still not sure Biden will be the Democrat candidate at this point. There's real possibility he will croak (God forbid), be officially declared unable to run for health reasons, or the DNC pulls something at the convention to put someone else in. There's also the ongoing lawfare against Trump that just might succeed, at least enough to keep him off the ballot this time.
There are too many variables at this point, IMHO, to make any kind of call. Hopefully before Super Tuesday, cause that's when my primary is, but likely afterwards there will be more direction.
