As the government shutdown continues, some House Republicans say they would vote for a so-called "clean" continuing resolution -- as the Senate has already passed -- to end the shutdown.

Cathy McMorris Rodgers, R-Wash., speak to reporters on Capitol Hill in Washington, Tuesday, Oct. 4, 2011, about an expected House vote this week on two separate bills aimed at delaying key Environmental Protection Agency air-pollution regulations on cement-plant emissions.

That number is now at about the level (21) that would be needed to pass a "clean" CR out of the House. That's because all 200 Democrats support a clean CR, and 217 votes are needed to pass it.

(Boehner has yet to allow a vote on it and may not because the vote violates the "Hastert Rule" -- i.e. doesn't have the support of a majority of Republicans. But as support in the House grows, Democrats will increase pressure on Boehner to do just that.)

As more Republicans and Democrats jump on -- or off -- board, we'll be keeping tabs on who is calling for a "clean CR." So check back often and click refresh.
