If Trump is found guilty on all the charges can he get jail time? Thanks.

Maybe. But it's not a certainty. A first conviction for a Class E felony (the lowest type) that doesn't involve violence very well might result in a non-jail sentence. But since it's a felony, it might involve jail time. Especially since Trump has not shown (and is not likely to show) any contrition for his actions.

But even if he eventually gets a jail sentence, it certainly wouldn't bar him from running for office. Trivially, even he didn't appeal, people who are granted pre-trial release don't get hauled off to prison straight from the courthouse. He wouldn't be sentenced for a few months after the trial, and not required to report to prison until sometime after that.

Trump would certainly appeal, though, and his attorneys will ask that any sentence be stayed until his appeal is reviewed, and that request is likely to be granted. So he'll be able to keep campaigning.

It's worth noting that even if he were imprisoned, he would still be the GOP nominee. He doesn't lose that status unless the GOP changes their rules - and they're not going to.
