Would not be surprised to see someone from the FBI turn whistleblower and go public with damning evidence about Trump. Other than that, we would need congressional Republicans to put their country before their party and do the right thing. In other words, we're screwed until midterms.
And just to reiterate what I've been saying for awhile, we have not heard the last of Paul Manafort. In my opinion, his Russian connections will be Trump's downfall.
