I know I'm not adding to the circlejerk in here right now, but I figured I'd report my results. 
Fear not, they are quite liberal. 
Sanders at 93% and Clinton at 82%. 
It's been a few weeks since I took it, but I do believe Rand Paul was in there around 55%.
The rest of them were significantly lower, anywhere from 5-30%. 
If I had to choose, my money would probably be on Biden, but I'd likely kill myself before I voted for Biden anyway.
