Can Nancy Pelosi Get the Votes?

Are there enough votes in the House to pass the Senate's health-care bill? As of today, it's clear there aren't. House Democratic leaders have brushed aside White House calls to bring the bill forward by March 18, when President Barack Obama heads to Asia. Nevertheless, analysts close to the Democratic leadership tell me they're confident the leadership will find some way to squeeze out the 216 votes needed for a majority.

Speaker Nancy Pelosi has indeed shown mastery at amassing majorities. But it's hard to see how she'll do so on this one. The arithmetic as I see it doesn't add up.
