Will he win again? Time will tell - he still needs to make it through the primaries, and I think Ron DeSantis is playing better with old school republicans than Trump ever did, but last time Trump did beat Mitt Romney who was pretty widely respected, so its certainly possible. If that happens, I think he is likely to beat Biden. A lot of people voted Biden because he was distinctly “Not Trump”, but his victory’s have been poorly televised, and his defeats make him look ineffectual and near senile (thanks Murdoch media).

He has already said that if he is elected he will pardon himself. That’s never been done before, so would almost certainly go to the supreme court, but since thats Republican controlled I would expect that to get rubber stamped. He’s not going to prison if he wins.

Just like every other election, it just depends how many corporations put money behind him.

He’ll be dead long before he’s sentenced to prison. If he doesn’t win, his usefulness is over with and he knows too much for the people that run the show to let him keep breathing.
