Several GOP senators oppose escalation in Iraq and speak eloquently about that opposition. You can see Senator Hagel in action here.
The only problem is that all but two of them voted to filibuster the anti-surge resolution they claim to support, including Warner (R - VA) who authored the damn thing.
So, after voting for the filibuster, Senators Hagel (R-NE) and Snowe (R-ME) sent a letter to Sen Reid advising they would prevent the coming recess to force a vote on the resolution......they both voted to filibuster. Sen Reid decided to has take them at their word and delayed the recess to have the vote on Saturday to end debate. It should be fun.
