Here's some footage from yesterday's McCain-Palin event in Waukesha, Wisconsin (it's the one our Ana Marie Cox called the angriest rally ever). The Washington Post described it this way:
There were shouts of "Nobama" and "Socialist" at the mention of the Democratic presidential nominee. There were boos, middle fingers turned up and thumbs turned down as a media caravan moved through the crowd Thursday for a midday town hall gathering featuring John McCain and Sarah Palin.
It's an increasingly common reaction at rallies for the Republican candidates. Hostility, racism, and threats of violence so disturbing that they prompt a an investigation by the Secret Service are now regular features at these events. But where is all the anger coming from? What's the reason for the venomous fury? Why are McCain supporters so full of rage?
