All house members are up for election every two years, did you mean “safe districts”?
I think Ross and Boren are not running for re-election. Their seats are up though.
John Barrow (GA) is in a new district and probably won’t get re-elected.
If you start a wave from LA through SC, John Barrow was the only white Dem re-elected in 2010. All the Dem blue dogs in the South were defeated except Barrow. But I don’t think he’ll survive the 2012 election.
