Well, what I'm hoping for is that it shows Trump is nothing more than a Russian agent completely beholden to Putin, mainly due to financial reasons. Considering everything, that seems to be a very high probability, and pretty much all doubt was removed from my mind when he gave that shitshow of a press conference in Helsinki.
Considering the previous indictments, Mueller is well known for being detailed. Hell, the last report included even specific unit numbers of the computers that Russian military officers used. I would imagine his final report will be just as detailed, and it will be irrefutable by even the most staunch of Republicans.
Another thing I'd love to see if Trump holds on until 2020 for some reason, is that Betoo Rouoke (sp) guy take the Texas Senate seat from Cruz, then go ahead and throw his hat in the ring for the 2020 run. Just because I'd absolutely love to see Trump lose the Presidency in 2020 to a Mexican.
