Nine House Democrats said Monday they're willing to switch their "no" votes to "yes" votes on President Barack Obama's health care overhaul, according to an Associated Press survey.

The lawmakers who indicated they might change their vote includes Brian Baird of Washington, Bart Gordon of Tennessee, and John Tanner of Tennessee, Rick Boucher of Virginia, Suzanne Kosmas of Florida, Frank Kratovil of Maryland, Michael McMahon of New York, Scott Murphy of New York, and Glenn Nye of Virginia.

Although Democrats hold a large majority in the House, House Speaker Nancy Pelosi, D-Calif., has struggled to secure enough Democratic votes.

It's partly because pro-life Democrats are objecting to using taxpayer money to pay for abortions.

Obama is expected to outline his plan for passing the overhaul in a speech Wednesday.

Meanwhile, Senate Democratic leaders have signaled they will use an unusual method known as "budget reconciliation" to try to push the overhaul through.
