Two main things:
1) That Trump would not win the election unless one of two things happened; Cheating, or aliens came down here and made us vote for Trump. Cheating has already been admitted to by Trump with regard to Don Jr. (can't be cheating by Trump or anyone on his staff to help him win). Again, I will not declare I have been proven right about this until the conspiracy is official.
2) That Trump is a criminal and will not skate. He will be impeached and convicted OR he will resign, OR he will not be re-elected in 2020 and face a criminal indictment. He likely will not spend jail time due to some combination of pardon and plea bargain. In any event, it will be proven that he is a HUGE criminal with the bulk of that proof coming from the Mueller investigation. People keep saying things like "Mueller never". Well, I say Mueller is coming, so that's what I will be proven right about.
Mueller is coming.
The clown is done. Trump will lose his presidency, his legitimacy, likely a lot of money, and possibly his freedom (though not likely the freedom for the reasons I stated). He will be considered the worst President and most corrupt President in the history of the United States whether he spends a minute in jail or not. THAT makes him "done".
