My bottom line view is that I simply don't have much criticism of a Republican, conservative, right winger, centrist, conservative Dem and so on selecting Trump over Biden in a general election.
I have a great deal of problems with the selection of Trump over Cruz, Rubio, Kasich, RDS, and Haley in the 2016 and 2024 primaries. Those are all different sorts of conservatives, and Trump was worse than them all. If the GOP makes a better choice in 2016 too, I believe the GOP and the country are better run subsequent to that election.
The Democrats suck on most issues (tho clearly I don't think they suck on Ukraine). I am not a Democrat, despite TJ's desires.
