On Twitter, I asked this morning, “Does anyone doubt that if the Keystone Pipeline ran through must-win swing states for Obama, he would have instantly approved?”

The NRCC is going after Democrats like Ohio Rep. Betty Sutton , arguing that by supporting Obama’s hesitation on the Keystone XL Pipeline, he is betraying “labor unions like the teamsters and segments of the AFL –CIO.

Announcer: Remember when President Obama said this about passing new jobs legislation?

Obama: We can no longer wait.

Announcer: But now it’s President Obama who wants to wait, to create up to 130,000 jobs with the Keystone pipeline bringing oil from Canada to the US.Announcer: If Washington does it Obama’s way that oil and those jobs will go to China. Congress has a chance to pass the pipeline jobs law before Christmas. The law has support of labor unions like the teamsters and segments of the AFL –CIO. But Betty Sutton is on the fence. Tell Sutton to support new jobs instead of supporting Obama.

Ads and robocalls will run in the districts of Reps. Betty Sutton (D-Ohio), Collin Peterson (D-Minn.), Nick Rahall (D-W.Va.), Jason Altmire (D-Pa.) and Mark Critz (D-Pa.). 

The National Republican Congressional Committee is already running ads. This one is running in North Carolina, hitting Heath Shuler for claiming to be a fiscal conservative but voting against the House GOP’s proposal to cut $61 billion from this year’s budget:

This one hits Rep. Nick Rahall of West Virginia for expressing support for higher gas taxes and supporting Obama’s moratorium on offshore drilling:

Hmm. Laugh at the cheesy background music if you like, but I think West Virginia Democrat Nick Rahall may run into trouble in his R+6 district for bragging about his early support of Obama, and how he helped mobilize the Arab-American vote for Obama in 2008.

Rahall looked vulnerable very early on, then looked pretty good in some polls. But Obama is phenomenally unpopular in West Virginia; if challenger Spike Maynard can tie Rahall to the president enough, this may be Rahall’s toughest race in a long while. Rahall’s first congressional win came in 1976.
