He hasn’t been sentenced yet and won’t be for months. Its possible that he won’t be sentenced untilafter the election. He’s also been indicted for paying the porn star, Stormy Daniels, hush money.

So, out-of-context, its just another rich dude doing money crime in the US. Its not like he’s been convicted of being a russian asset or doibg war crimes. Convention is to give him a slap on the wrist. But external political pressures and him being a unique dumbass to the judge will probably result in a tougher sentencing. But I doubt there will be any prison time, even white collar.

Also you cans still run for president from prison. Eugene V. Debs ran as the Socialist Party candidate while jailed for sedition during WWI.
