The Senate narrowly approved President-elect Barack Obama's request for $350 billion in financial bailout money on Thursday.

The vote averts a politically awkward showdown between Obama and Democratic leaders in Congress. Obama had warned that he would have vetoed legislation blocking access to the second half of the $700 billion financial rescue funds known as the Troubled Asset Relief Program, or TARP.

Both houses debated Obama's call to release another $350 billion from the financial bailout package, but the vote that mattered most was in the Senate. Despite bipartisan anger over the Bush administration's handling of the program to date, Democratic allies of the incoming president prevailed on a vote of 52-42 that will permit the release of funds within days of Obama's inauguration.

The vote followed a commitment by Obama to use as much as $100 billion of the money to help homeowners facing foreclosure.

The 44th president-to-be was at his transition office across town from the Capitol -- and President Bush relegated to the role of virtual onlooker -- as events played out at the dawn of a new Democratic era in government. Obama has called for swift and bold action to confront an economic debacle unrivaled since the Great Depression.

In a written statement, Obama welcomed the stimulus blueprint as "a significant downpayment on our most urgent challenges," and said, "it will contain the kind of strict, independent oversight that will allow the American people to hold Washington accountable for how and where their tax dollars are spent."

The outlines of the economic stimulus measure reflected a change in political priorities, with an emphasis on spending and tax breaks designed to encourage production of alternative energy sources, make federal buildings more energy- efficient and weatherize homes.

At the same time, more traditional anti-recession spending was built in. There was more than $130 billion for health care, much of it to help states cope with the rising demand for Medicaid, the health care program for the low-income and a recession-era refuge for the newly laid-off.

More than $100 billion was ticketed for education, in part to help local school districts avoid the impact of state budget cuts. Billions more would increase spending for food stamps and unemployment benefits and finance expanded worker retraining programs.

A written summary showed $30 billion for highway construction, $10 billion for mass transit and rail, and $3 billion for airport improvements.

In all, the outline called for $550 billion in new spending and $275 billion in tax cuts. And the $825 billion total is virtually certain to grow as the legislation advances through Congress.

Initial Republican reaction was negative -- and played on Obama's popularity to make a point.

"At first glance, it appears that my Democratic colleagues think they can borrow and spend their way back to prosperity with a half-trillion dollars of new spending and less tax relief than President-elect Obama has been talking about," said Republican Rep. John Boehner of Ohio, the party's leader in the House.

Democrats hold expanded majorities in both houses as the result of last fall's elections, and enactment of the stimulus measure is scarcely in doubt.

At the same time, lawmakers made clear they will not hesitate to substitute their own priorities for Obama's.

The president-elect's call for a business tax credit for each new job created was jettisoned by Democrats who questioned its value and preferred to use the money elsewhere. They agreed to Obama's separate proposal for a tax cut of $500 per worker and $1,000 per working couple. The documents made public did not say whether the money would come in the form of a one-time check or an adjustment in paycheck withholding.

The measure does not include money to help middle- to upper-income taxpayers ensnared in the alternative minimum tax, which was originally designed to prevent the extremely wealthy from avoiding payment of taxes but now threatens more than 20 million tax filers.

Several officials said the Senate was likely to include that provision in its version of the bill, a step that could push the overall total close to $900 billion.

Money for the financial bailout was a tougher sell by far.

Several newly elected Democrats campaigned as opponents of the program, which was launched last fall with an initial $350 billion, and lawmakers in both parties have expressed unhappiness with the Bush administration's management of the effort.

Obama lobbied Democrats in private earlier in the week not to stand in the way of release of the remaining $350 billion, and a top aide followed up with a written commitment to Reid.

In it, Lawrence H. Summers, pledged that $50 billion to $100 billion would be dedicated to a "sweeping foreclosure mitigation plan for responsible homeowners."

In search of Republican support, Summers also said that apart from a commitment to help the Big 3 automakers survive, the new administration did not intend to intervene financially in individual industries outside the financial sector.

The stimulus measure, meanwhile, encompassed a bewildering array of programs, from money to make broadband available in rural areas to support for scientific, biomedical and climate change research.

It also proposed an increase in Pell Grants for college students of $500, and would forgive repayment of a $7,500 tax credit that Congress passed last year as a loan for first-time homeowners.

Another $50 million would be spent "to put people to work making monument and memorial repairs at cemeteries for American heroes," according to an information sheet distributed by Democrats.

The summary claimed "unprecedented accountability" and said the bill would include no earmarks, the pet projects that lawmakers are fond of promoting.

In addition, Democrats said all announcements of contract and grant competition would be posted on a Web site to be created by the new administration.
