I would prefer if he did not run. He's too old, and too viscerally disliked by Independents whose support we will need, especially given the need to overcome the inevitable Democrat cheating.
The problem is: who else to support if you are a Conservative? Ron DeSantis would be an obvious choice, but he may well not run. I like John Kennedy of Louisiana, but he's also older and I doubt he's interested. The big risk is getting a spineless moderate or some swamp creature as the GOP nominee, which is, as we have seen in the past, a real issue.
In that case, I'd much rather have Trump, baggage and all.
