As I see it, if Trump gets convicted and I think that's likely, his options, given he wins it all, are limited to a few and none of them are good.
1) resign and go to jail
2) try to "pardon himself" which just won't sit well with the public at all.
As a matter of fact, I think Trump stands a good chance of winning everything, getting elected President, and they will go after him twice as hard. And again, see my two solutions above.
This could all be solved by nominating someone without these issues IMO.
