I was wondering if this year is any worse than 2010, wasn't following them in that midterm.
They certainly seem out of sorts and blaming everyone for their losses. 
Lots of infighting too. 
I think part of the problem is unlike 2010, the pollsters did their best to build up the Democrats hopes by declaring races 'close' that weren't even in the same universe, with the hopes of energizing Dems and sending them to the polls, while depressing opposition turnout. It backfired. BIG TIME.
Wendy Davis *NEVER* stood a snowball's chance - Neither did Grimes - Yet many had those races and others like them as 'too close to call'. Also, the margins of defeat in many of these races were wider than the Grand Canyon, so wide that the old 'stolen election' canard doesn't even play well with many.
Davis lost Texas by nearly 21 points. - So much so that her campaign is blaming the beating on Cracka-ass honky women & Ebola.
McConnell beat Grimes by 16 points. - Reality says that a beating like this can only happen when the race was never close, barring an epic October Surprise. Yet the Dems thought it was within the realm of winnable.
With results like this coming in, MSNBC and others than turned to governor's races, hoping for big wins there. Nope.
etc etc etc..
So now the Dems are super deflated & angry. The media campaign backfired, leaving many of them devastated by insurmountable defeats they didn't see coming. Too bad, primitives.
