Last March, 34 House Democrats joined all 178 Republican in voting against Obamacare. With today’s vote, the new GOP majority will be eager to tout meaningful bipartisan support for repeal. They are likely to be left wanting.

One obvious reason is that there are simply less Democratic votes to go around. Of the 34 Democrats who opposed final passage of the health care bill, only 13 survived the midterm elections in November, which saw the conservative Blue Dog coalition reduced by more than half. Many lost despite aggressive efforts to distance themselves from their own party. Rep. Gene Taylor (D., Miss.), for example, had signed a GOP pledge to repeal health care reform, but was still defeated at the polls by Republican Steven Palazzo. Not only that, but the Obama administration — anxious to keep Democratic defections to a minimum — is said to be whipping the vote “aggressively.”

As of last week (before the tragedy in Tucson), only two of those remaining 13 — Reps. Dan Boren (D., Okla.) and Mike Ross (D., Ark.) — have said they plan to back repeal.

Eight others — Reps. Heath Schuler (D., N.C.), Larry Kissell (D., N.C.), Stephen Lynch (D., Mass.), Jason Altmire (D., Pa.), Tim Holden (D., Pa.), Collin Peterson (D., Minn), Dan Lipinski (D., Ill.) and Jim Matheson (D., Utah) – have said they intend to vote no.

Reps. Ben Chandler (D., Ky.), John Barrow (D., Ga.) and Mike McIntyre (D., N.C.) have yet to signal their intentions, though McIntyre did say shortly after the law was passed in March that he would support its repeal.

Alex Cortes, chairman of DefundIt.org, has been leading an effort by conservative groups urging these Democrats to support repeal. He released the following statement today, praising Boren and Ross:

If only their colleagues had their same intellectual consistency and recognize the common-sense reality that if you are truly against something, then you will take the actions necessary to get rid of it. Thankfully there are still several hours left before the vote and I suggest some persuasive tea time may be in order.

Cortes told National Review Online that any Democrat who opposed the original bill and didn’t vote to repeal it would be engaging in “the heart of dishonesty” and warned that every politician who opposed repeal did so at their own peril because “the American people are on our side.”
