GOP election disaster good for conservative publishers?

The AP has a story speculating that the Democratic takeover of the House and Senate (Sen. George Allen just conceded) might be a good thing for conservative publishers.

The opposition has certainly suited liberal authors and publishers -- complaining is easier than espousing a vision, and when your supporters are angry, it's a good market opportunity. But while criticism of liberals is certainly a valid subject for books, I think conservative readers are going to want "that vision thing," too.
