A Sad Truth about "Undecided Voters"

From Duncan Black:

I didn't quite catch who it was, but it was refreshing to hear someone at NPR point out that "undecided voters" don't know or care much about politics. I feel like our entire campaign coverage is directed at mythical people who spend months with furrowed brows studying every little bit of trivia about the campaigns before finally making their decisions. Most of them are stupid about politics and are barely interested.
