"Best case scenario" is we get a President Paul Ryan.  And that's only IF there's insurmountable proof that Russia had a hand in the election and Trump's campaign not only knew, but actively encouraged it.  If that is the case, they'll be on trial for treason and unable to assume the office.  It then falls to the Speaker of the House.  However, the only way the occurs is once the electoral votes are official.  Which is Monday.

I don't know where other progressive moderates (such as myself) are on the issue, but I may actually be okay with an internal GOP coup removing Trump and installing Pence.  Beyond all of his racist, misogynist bullshit, Trump's actions in the days following the election - from his cabinet posts to his breaking of all protocol (which has already created an international incident), to the victory tour - have tainted the office to such a degree that having a creep like Pence in there would be a relief, because he'd at least BE there and take the fucking job seriously.  

I know Pence would be pushing the same agenda as Trump, but we're now at the point where style counts, and a bloated, tactless, and gilded clod like Trump is the antithesis of the style the office calls for.
