'No' vote on healthcare reform not helping Democrats seeking reelection

Four House Democrats who voted against their party's healthcare reform law had already lost reelection by 10 p.m., and many more were expected to follow suit before night's end.

And Sen. Blanche Lincoln (D-Ark.), who first voted for the law and later against the healthcare reconciliation bill when her vote wasn't as vital, has lost reelection to Republican Rep.

Democratic Reps. Lincoln Davis (Tenn.), Chet Edwards (Texas), Glenn Nye (Va.) and Rick Boucher (Va.) had clearly lost by 10 p.m. In all, as many as 27 of the 34 Democrats who voted against the president's healthcare overhaul could lose their seats in the midterm elections, according to a review of The Cook Political Report's Nov. 1 list of competitive House seats.

And Democrats could lose yet more seats previously held by healthcare reform foes.

Berry, a yes vote the first time around, voted against the healthcare reform bill in March out of concerns it wasn't clear enough on abortion and did too little to control costs.

Rep. Charlie Melancon (D-La.) also left his seat wide open when he retired to run for the Senate. Republican Jeff Landry is ahead of Democrat Ravi Sangisetty in that race.
