Found it:
“One of the goals of having the seven Blue Dog members band together is to guard against leadership picking centrists off one by one with side deals, as they feel was done during the energy vote.
The group includes all the Blue Dogs on the committee except for Rep. Jane Harman (D-Calif.). They are Reps. John Barrow (D-Ga.), Bart Gordon (D-Tenn.), Baron Hill (D-Ind.), Jim Matheson (D-Utah), Charlie Melancon (D-La.), Ross, and Zack Space (D-Ohio). “
All would be at risk in the 2010 election cycle. I am telling ya it wouldn’t be the first time fiscally conservative dems have kicked the powers in the nuts
