The president is reaching out to a number of lawmakers who are undecided about how they will vote. Democratic leaders are only about seven votes away from getting the 216 votes they need to pass the bill in the House, but roughly a dozen Democratic members of Congress have still not declared whether they will support it. Some of these Democrats are either unhappy with the deletion of Stupak's abortion language while other liberal members say the bill doesn't go far enough to protect Americans.
Even Vice President Joe Biden has been constantly working the phones.
"They say, 'Well Joe, look man, I mean, you know, you guys haven't messaged this very well,'" Biden told ABC News' Jake Tapper in an exclusive interview in Durham, N.C., Thursday. "And, 'you know, this thing has gone on so long.'"
Biden said his response to worried lawmakers is simple: "The proof of the pudding is in the eating."
"I'm telling you, you know, pre-existing [conditions], they're going to be covered. You know we're going to control the insurance companies," the vice president said. "You know people aren't going to lose their health care with their employer like is being advertised."
Biden said once these provisions take effect, and the American people feel the impact, lawmakers who vote "yes" will reap the benefits.
Hours away from a health care vote, the fighting on the House floor has intensified.
"They're going to continue to ram, ram, ram this bill through the Congress," House Minority Leader John Boehner, R-Ohio, told reporters Thursday.
Democrats were touting a preliminary report from the Congressional Budget Office, which estimated that the health care bill will cost $940 billion over the first 10 years and will reduce the deficit by $138 billion in the same time period.
"The bill is the biggest deficit reduction bill that any member of Congress is going to have the opportunity to vote on," House Majority Leader Steny Hoyer, D-Md., said Thursday.
Even President Obama hailed the bill as the "most significant effort to reduce the deficit since the Balanced Budget Act" of the 1990s.
Today, the president will once again take the health care push to the road by holding a rally in Fairfax, Va., to drum up support for the bill and convince skeptical Democrats that they need to vote "Yes."
