President Barack Obama and the Democratic congressional leadership are pushing hard with all of their political might to get undecided members of Congress to vote for the health care reform bill.
So far, it's unclear whether or not they have the necessary number of votes to pass the legislation.
Both sides of aisle are spending millions of dollars in advertising, targeting the undecided legislators.
"There's no decision yet on what the process is going to be, there's nothing back from the CBO, there's no commitment yet from the Senate that they can get 51 votes, and there's no bill to show me what's in it," said Rep. Dina Titus, D-Nev., a freshman who voted "yes" last year.
"So until those things get resolved I'm staying uncommitted," Titus added.
Meanwhile, former GOP House Majority Leader Dick Armey told ABC News he thinks Congress will be able to pass the measure.
But Rep. David Dreier, R-Calif., disagreed, saying the Democrats are actually losing votes.
"They twist arms and try to work back room deals...Americans are voting no," he said.
Republicans are urging voters to call their representatives and urge them to vote against the measure.
Rep. Mario Diaz-Balart, R-Fla., called the bill "a flea infested, tick infested, parasite infected, special interest infected, wet, smelly dog."
Meanwhile, there are reports that if House Speaker Nancy Pelosi, D-Calif., finds herself short of votes, she'll use a little-known legislative procedure to pass the bill without a vote. According to the Washington Post, the House can vote instead on a set of 'fixes' to the Senate bill and avoid a vote on the House bill.
The Democrats only have a few days left before the final vote is expected to be taken.
