I predict that Dem-on-Dem violence will far surpass any Dem-on-Rep violence this summer. Imagine how surreal that will be: supporters of a chubby blonde woman are going to come to blows with police and with other Dems.
Blood will be shed over...Hillary Clinton. God, that is so twisted. I LOVE it. 
I'm practically salivating in anticipation of the sight.
And don't forget--this won't be only between the rabid Obamaites and the supporters of the worthier Democrat candidate.
There's the primitives and trouble-makers who are upset that Barry "Goldwater" Obama isn't far enough "left" to suit them, and so they'll be in the mix too.
It's just going to be so much fun.
