The hush money one is the first one to actually go to trial, so it’s mostly that. The documents case is basically suppressed until they can somehow get rid of this judge, and the other 2 cases are also being held up in places.
The hush money case isn’t likely to put him in prison though, I don’t think there’s any precedent of a politician going to prison for that. And of course there’s going to be appeals that can easily push it until past November.
