And all 23 of them will campaign in 2014 on having voted for legislation to undue the damage from Obamacare. Well done, GOP.

Via Ballot Box:

Nearly every one of the Democrats’ most vulnerable incumbents split with their party on Friday and voted for a Republican measure to allow Americans to keep their insurance plans under ObamaCare.

All but three of the 26 members of the Democratic Congressional Campaign Committee’s Frontline Program — the designation for their most endangered incumbents — voted for the bill.

They joined 16 other Democrats in supporting the measure, which passed the House 261-157. Four Republicans voted against it.

The bill had already picked up four Democratic sponsors: Reps. John Barrow (D-Ga.), Mike McIntyre (D-N.C.), Patrick Murphy (D-Fla.) and Kyrsten Sinema (D-Ariz.). All four are top Republican targets in 2014.

Other vulnerable Democrats voting in favor of the bill include Reps. Carol Shea-Porter (D-N.H.), Nick Rahall (D-W.Va.) and Jim Matheson (D-Utah).

The defections reflect the political realities facing Democrats as the botched rollout of the healthcare law has caused widespread public backlash against the law and the party. Democrats have seen the polling advantage they gained following the government shutdown erased in the wake of issues with the law.
