Think the 2010 elections were bad for the "Blue Dog Democrats" when 28 of them lost?  2012 could see their numbers dwindle even further.

From Hotline on Call:

Rep. Dan Boren's, D-Okla., announcement that he won't seek another term will make the group of moderate to conservative Democrats within the caucus even smaller, following 28 Blue Dogs who either retired or were defeated last cycle.

Another Blue Dog who only barely survived, Rep. Ben Chandler, D-Ky., will get a rematch from the man who nearly beat him last time, attorney Andy Barr. But Chandler could be one of the few Southern Democrats who is actually helped by redistricting. Rep. Jim Matheson, D-Utah, on the other hand, isn't likely to be helped in redistricting, and he made it known this week that he's considering either running for the Senate or for governor, and with his family's history in the state, he could run strong statewide too.

Republicans only have a few targets they narrowly missed last time -- look for them to ramp up pressure especially on the dying breed of Southern Democrats in North Carolina, Georgia and Arkansas.
