Will physical fighting occur between Obama and Clinton supporters?

[classical liberal]

Forget the supporters, that's how they should decide the nomination - a death match between the two candidates, right up on stage at the convention! "Let's get rrrready to rrrrumble!" I expect Hillary to fight dirty though, I bet she'd kick Obama in the balls and everything.

In so doing, she'd probably pick up some female super-delegates who were as yet undecided.
