What we can expect if this gets to the Pennsylvania primary:

The race between Hillary Clinton and Barack Obama for the Democratic nomination continues to heat up — but in one Montgomery County, Pa. household, the debate turned violent.
Prosecutors say that two brothers-in-law tried to settle the presidential race on the kitchen floor of a Collegeville, Pa. home.
Jose Ortiz, 28, is now behind bars on felony assault charges after prosecutors say he stabbed Sean Shurelds inside a home in the 100 block of Honeylocust Court.

District attorney Risa Ferman says a heated debate over the candidates escalated into violence:
“One is a supporter of Barack Obama, the other is a supporter of Hillary Clinton, and an argument of words turned bloody when one brother-in-law tried to choke the other and the victim then responded with a knife and stabbed his brother-in-law in the stomach.”
