Dems unsure about changing votes for health care

A top House Democrat said Sunday he believes Congress will pass a health care bill, but three fellow Democrats who opposed overhaul legislation last fall aren't committing themselves to backing President Barack Obama's late push. The House and the Senate approved different version of the legislation by narrow margins. Merging the bills became more complicated when Senate Democrats lost their filibuster-proof majority in January. House members are reluctant to approve the Senate plan on the promise that senators will tinker with provisions House members find objectionable. Still, that wobbly bridge appeared to be the clearest path to meeting Obama's goal of Congress passing a health care bill by March 18, when he leaves on a trip to Asia. Central to success is persuading some of the House members who voted against the original legislation to go along with the Senate bill.
