Yep, the GOP games have begun in earnest.

This afternoon, Senator Corker basically threatened to walk away from the START Treaty over “more campaign promise types of issues.” Corker claims the votes on DADT and DREAM are “poisoning the well” and he basically threatened to stop movement on the START Treaty.

Via the ever vigilant Igor Volsky:

As Igor notes:

Corker’s description of DADT as “partisan” is surprising in light of the increasing Republican support for the measure. Republican Senators Susan Collins (ME), Olympia Snowe (ME), Scott Brown (MA) and Lisa Murkowski (AK) have pledged to vote for the stand-alone repeal bill.

Corker said he hopes saner minds prevail. Yeah, we’re hoping that saner minds prevail.

Will Collins, Snowe, Brown and Murkowski play along with Corker or still vote for the standalone DADT bill.

Greg Sargent has more:

This isn’t really a threat on Corker’s part. Rather, he’s saying — in a more-in-sorrow-than-in-anger way — that his GOP colleagues will be less likely to support START unless Reid drops his plan for DADT and DREAM votes right away.
