How stupidly optimistic can we get about 2016? I'm glad you asked!
Against Donald Trump, will Hillary Clinton (or you know, one of the other losers) target the demographically rich GA/AZ? Or the more Dixiecratic MO/IN? Presenting the "whynotboth.jpg" approach:
Just four votes shy of clearing 400 electoral votes. Damn you, Arkansas! Don't worry, the Senate Democrats will be proud to add you to their column as one of the biggest surprises of the night.
Democrats sweep every contested Senate election, with the lone exception of Kentucky. Sorry, but we've got to be realistic in at least one regard here. The good news is that after witnessing the complete blowout, Lisa Murkowski, Susan Collins and - I dunno, some asshole? - see the light and caucus with the Democrats, giving them a 60 vote supermajority. Not that it matters, because Chuck Schumer's first act as Majority Leader is obliterating the filibuster, so everything passes with a simple majority of 51 votes. But while symbolically powerful, it's still meaningless in the face of a Republican House, right?
Wrong! Trump is so disastrous that Democrats swing a miraculous 39 seats, putting them nine seats over the majority. What's more, few of these seats are in the deep red territory that bolstered the Democratic caucus through 2010, so while they will certainly lose seats in the next midterm, it might not be quite the bloodbath we've come to expect from the Obama years.
Oh yeah there's governor's races too. Republicans only win two because fuck them. Jack Dalrymple and Gary Herbert counting their lucky stars that Heidi Heitkamp and Jim Matheson didn't take the plunge.
