Political Violence: Pelosi Tears Up

What is the Speaker talking about? KKK? Nazis? Radicals? SDS? The Weather Underground? Harvey Milk, Republican... murdered in San Francisco by a Democrat? Racism? Wasn't the violence of the 60's and 70's called for or perpetrated by Leftists? Is Ms. Pelosi talking about the Tea Parties and the Town Hall Meetings? If so, the rhetoric is nothing like that of the time period she speaks of. NOTHING LIKE IT!
