The first year he did much better in hiding it than i expected.
The very easy schedule and friendly press helped to be sure, but they kept him from being too obviously messed up, to the crat voters.
Now, even with a year of practice hiding it, they can't anymore. I think it is getting worse quickly and they know it can't go on long enough to win in 2024.
His handlers are desperate to hold him together until Nov elections. 2 more years of this getting worse is more than even the few semi realistic crats will vote for.
