Constructively, can you name any decent Republican candidate to succeed Trump? They’ve all been banished by him. Anyone left is complicit in his criminal enterprise, if not participating in it.

"Banished" by Trump? Trump doesn't have that kind of power to "banish" anyone. People too closely associated with DJT will be somewhat politically radioactive, though.

The short list of the S-tier Republican candidates in 2028:

-DeSantis. Wildly successful governor of Florida. Will be an immediate front runner and has already all but announced he's in.
-Rubio. Has had a very good run as SecState and National Security Advisor and isn't tied to the hip.
-Glenn Youngkin. Former Governor of Virginia. Popular former Governor - can he raise enough money?

Vance I think is done. He's widely known as the architect of the Iran MOU that many blame for the war dragging on and it too closely tied to Trump.

Other people who will run are Ted Cruz (3rd or 4th time's the charm), maybe Tim Scott, maybe some other Senator.

It's highly unlikely that a sitting Senator gets the nomination; that's where the democrats traditionally draw their candidates from. The GOP tends to go with governors (which are better choices due to their experiences running states).

Of that list, DeSantis and Rubio are the strongest with Youngkin as the dark horse.

Alas, the guy that would have been the best President of the last 50 years is now too old and is just finishing his post-retirement job as the interim President of Purdue University (former Governor of Indiana Mitch Daniels). His wife never wanted him to run and that's a real loss for the country - he would have been absolutely fabulous. Fortunately for us alums he had an amazing run as Purdue's President and famously Purdue never raised their tuition for 11 straight years while he was in charge (which is especially impressive given the spiraling cost of college *and* how good of a school Purdue is). Too bad.

Got to meet him once in person when he came out to Seattle. Great guy.
