I don’t think it would. Because one of his best weapons is his ability to constantly run his mouth (virtually or otherwise), and in jail, he’s not afforded that luxury by virtue of being a presidential candidate. And I’m talking about jail, not prison.

But even with prison, he wouldn’t be able to stay relevant as well as he does currently. He would be forced into regular silence, and a candidate that doesn’t stay relevant in the public zeitgeist is doomed to lose.
