It looks like there are four candidates for three spots, so one person won't make it. Melissa Baten Caswell is incumbent and seems well-regarded. Camille Townsend is two-term incumbent and well-known, though some don't like her. Heidi Emberling is a newcomer with an educational background, but a relative unknown. Ken Dauber has created a stir with his efforts over the last year, and has gotten his name in the paper a fair amount, though he has polarized people with some of his issues and methods. The PA Weekly seems to support him.

So who is the odd-person out?
