In November, Congresswoman Betsy Markey was among 39 Democrats who voted against the House version of the health-care-reform bill, saying it didn’t do enough to control government spending. But a new version of the bill, causing a ruckus on the Hill this week, is good enough to get Markey’s approval, thanks to a provision that would clamp government spending.

“Particularly in the out years, there’s significantly more deficit reduction, and I have to say this is going to be the largest deficit-reduction bill that I will ever vote for,” she tells the Fort Collins Coloradoan.

Markey, The Washington Post writes, “is a politically significant convert” as a freshman Democrat from a district that could swing Republican come November.

Still, it is unclear whether the bill has enough support. Markey’s announcement is considered early evidence to some insiders that House Speaker Nancy Pelosi is scrambling for votes, notes Politico. Because she is “facing a tough re-election, most folks viewed Markey as a break-in-case-of-emergency vote for the bill.”
