How angry are Americans?

Kevin Drum

From Kevin Drum at Mother Jones:

It seems as though I've heard about the seething anger of the electorate before nearly every election in my life. Joe Klein takes a drive through the heartland every few years and reports back about this. But all sorts of polling evidence suggests that Americans aren't really all that unhappy in general and not really all that angry about the government. No more than usual, anyway. Now, maybe this year really is different. Maybe voters are more responsive to angry appeals even if they aren't especially angry in general...
