Every election year, we in the commentariat come up with a story line to explain the result, and the story line has to have two features. First, it has to be completely wrong. Second, it has to reassure liberals that they are morally superior to the people who just defeated them.
In past years, the story line has involved Angry White Males, or Willie Horton-bashing racists. This year, the official story is that throngs of homophobic, Red America values-voters surged to the polls to put George Bush over the top.
This theory certainly flatters liberals, and it is certainly wrong.
