John, Trump has little incentive NOT to run, or at least say he's running because he can pull out at any time. He has no concerns about the Republican Party beyond his ownership.
Should he get the nomination? Most likely. The party is MAGA. DeSantis is a young possibility but lacks the endearing personality of Donald.
Whatever, the Democrats need to refresh themselves to retain the White House. The first is to move Joe Biden out of the way should he not do it voluntarily. Alas, a cleverer Joe would have announced his step back from running for a second term months before the Mid-Terms. This would have licensed energetic presidential hopefuls to hit the trail and help their colleagues across the country (instead of now reaching for dead wood like the Clintons). A huge mistake that too few realize.
My article "Please, Joe, Not Another Term" is still relevant.
Many thanks, John. Always thoughtful.
