Sen. Collins then:

Raju reports that "several other GOP senators" said they would jump on board with Coburn blockade if the Democrats try to extend benefits without using the pay-go rules to fund them again. Among the supporters, apparently, is Sen. Susan Collins (R-ME), who attempted to stop Bunning the last time.

"The last time was an emergency situation--but we can't keep doing one-month extensions that aren't paid for," Collins told Politico.

And yesterday:

The chamber voted 60 to 34 to proceed on a measure that would extend unemployment insurance, subsidies for the COBRA health insurance program and federal flood insurance through May 5. Four Republicans -- Sens. Scott Brown (Mass.), Susan Collins (Maine), Olympia J. Snowe (Maine) and George V. Voinovich (Ohio) -- joined every Democrat present in voting to move the bill forward, making it likely that the measure will pass in a final tally this week.
