The $85 billion in tax-cut savings included $5 billion by tightening eligibility for tax credits for workers and families with children, and $9 billion from scaling back business tax breaks.
The president called Reid late Thursday night. Emanuel called him five times Friday morning and joined the negotiations in person in the afternoon.
The White House announced that Obama would campaign for the bill early next week in Indiana and Florida. The president will also hold his first prime-time news conference Monday, another platform to push for the legislation.
Offering a sample of the way Obama will probably target skeptical lawmakers, aides to the president talked Friday about the effect his plan would have on specific states -- aiming, by implication, at the lawmakers who represent them.
Gibbs, the White House press secretary, explained the loss of nearly 600,000 jobs in January as "the equivalent of losing every job in the state of Maine."
"In the past two months, the economy lost 1.2 million jobs," he said. "That's basically losing every job in Pittsburgh or in Cleveland."
By taking his campaign on the road, Obama is making himself the public face of the stimulus legislation, an attempt to supersede the less popular congressional Democratic leadership, some analysts said.
With so much attention focused on the debate in Congress, Americans have begun to associate the stimulus bill with Democratic officials such as Senate Majority Leader Reid and House Speaker Nancy Pelosi of California, they said.
Obama's travels are "a way of transferring the legislation from a Pelosi-Reid face to an Obama face," said Peter Hart, a Democratic pollster. "And the Obama face is a more attractive one."
Still, among Republican lawmakers especially, disenchantment with the stimulus package runs deep. These Republicans suggested that Obama's roadshow would not influence their votes.
Sen. Bob Corker (R-Tenn.) said in an interview that Obama's trip reflected a recognition on the president's part that the stimulus package "is a fumble."
Corker added: "I wish that instead of going to Indiana and Florida, he was sitting down with his [Democratic] colleagues here in the Senate and letting them be honest with him. I think that many of them realize what a mistake this is."
In the Senate, the challenge facing negotiators was to trim the bill enough to win Republican support without losing Democratic votes. The fact that only a handful of Republicans signed on to the agreement was a blow to Obama's hope that the bill would pass with support of a broad bipartisan majority. But at least three Republicans were needed to secure the 60-vote majority necessary to overcome procedural hurdles.
