In Time of Victory, Why is the Left So Angry?

"They see that they have a very small window of opportunity to do all the things they want," Anderson went on. "They see the window of opportunity as small because they know in their deepest hearts that the vast majority of the American people wouldn't go for all of the things they want to do." So they are frantic to do as much as possible before the opposition coalesces. And the tea parties might be the beginning of that coalescence.

Then there is the question of self-image. Watching Garofalo and Olbermann discuss the tea parties, it was impossible to avoid the sense that they saw themselves as two good people talking about many bad people. "One of the things about narcissism is that it looks like people who are just proud of themselves and smug. But in fact, narcissism is a very brittle and unstable state," Anderson told me. "People who are deeply invested in narcissism spend an awful lot of energy trying to maintain the illusion they have of themselves as being powerful and good, and they are exquisitely sensitive to anything that might prick that balloon."

Again, the tea parties could represent a threat. What if the protesters weren't racists, weren't violent, weren't mentally defective? What if their point was legitimate, or even partly legitimate? Those are questions better batted down than answered.

Finally, there is the sense of anxiety and fragility that stems from the liberals' newly won power. They control everything in government, and some fear what the responsibility of governing is doing to them.

Their president of hope and change is against a special commission to investigate Bush-era terrorist interrogations. He is escalating the war in Afghanistan. He seems determined to bail out the nation's richest bankers. For some on the left, it can be difficult to abide those actions and still maintain the image of one's self atop the moral high ground. So they lash out at the easy target presented by the tea parties.

And that is how political triumph can produce anger and unhappiness. Don't be surprised if there is much more of both in the days to come.
