The district you mention, HD49, that's not strange it seems to be relatively moderate for the PVI?
I mean, I just made some search about the current representative, and he won fairly easily in 2006 (60-40), and he wasn't even challenged in 2012. I just saw his record and he seems to be pro life, pro gun and anti civil union. That's quite conservative for a "moderate" district, so that's strange democrats didn't even compete in this district.
I'm sure muon2 will be very grateful for this information.
