WASHINGTON — A proposed final report by President Obama's deficit commission warned Wednesday of a fiscal "reckoning" unless Americans commit to major sacrifices, but the warning may fail to spur lawmakers to action without support from most members of the bipartisan panel in an upcoming vote.

The report, ominously titled "The Moment of Truth," immediately drew the support of half the 14 members needed to move it to Congress for its consideration. Only one member — Rep. Jan Schakowsky, D-Ill. —stated she would vote against it, while most others said they needed additional time to decide.

Pass or fail, members said they thought some of the commission's work could reach the floor of Congress. "There's nothing magical about the 14 votes. We must advance the debate," said Rep. Jeb Hensarling, R-Texas.

A final vote Friday will determine whether the recommendations lead to action or collect dust along with countless other blue-ribbon committee reports.

"If we do not act soon to reassure the markets, the risk of a crisis will increase, and the options available to avert or remedy the crisis will both narrow and become more stringent," states the document by the panel formally known as the National Commission on Fiscal Responsibility and Reform.

The final recommendations are largely the same as an initial plan issued last month: a cap on discretionary spending through 2020, an overhaul of the tax code, and reforms to Social Security that include raising the retirement age. These steps would slash the federal deficit by $828 billion by 2015, and achieve $4 trillion in deficit reduction by 2020.

But some concessions were incorporated to draw greater support among the 18-member panel. A proposal to drastically limit the home mortgage interest deduction was eased. On Social Security, the focus of significant criticism weeks ago, the panel proposed a hardship exemption for workers based on factors such as physical demands of labor and lifetime earnings.

Still, the head of the AFL-CIO, the nation's largest labor union, charged that the panel had told working Americans to "drop dead."

Members of the commission said there was no way forward without difficult choices. Sen. Richard Durbin, D-Ill., said that raising the retirement age by one year is "hardly radical."

"They won't like me for saying it, but what you have suggested... is acceptable to me," Durbin said at a meeting of the panel.

But Durbin, the No. 2 Democrat in the Senate, was not prepared yet to offer his final assessment. Neither were a majority of the other elected officials on the commission.

Only Sens. Kent Conrad, D-N.D., and Judd Gregg, R-N.H., the chairman and ranking member, respectively, of the Senate Budget Committee, immediately supported the plan.

"We risk the United States becoming a second-rate economic power," Conrad told reporters after the nearly three-hour session. "That is what is at stake. The economic future of this country is at stake."

Schakowsky rejected the report "for the reasons of equity."

"We talk about shared sacrifice. I think these numbers indicate that sacrifice, in fact, has not been shared, that some people have lost and others have significantly gained over the last several years," she said at the meeting.

Other members outlined elements of the plan they could support and others that troubled them, indicating they were not yet prepared to state a position.

Just five "no" votes would be enough to defeat the proposal, which would be nonbinding in any event.

A successful outcome — approval by 14 members — would move the package of proposals to Congress for its consideration. Senate Majority Leader Harry Reid, D-Nev., has pledged to hold a vote if approved.

But even if it is not approved by 14 members, some members expressed their commitment to continue negotiating on proposals that could be introduced in the 112th Congress.

"We'll see what happens on Friday, but I intend to stay at the table," said Rep. Xavier Becerra, D-Calif.

Commission aides point to two imminent debates that will ensure its work lives on — the fate of Bush-era tax cuts, and a looming vote next spring to raise the federal government debt ceiling.

"It's going to be hard to pass a debt limit increase without showing serious action on the deficit," said a commission staffer, speaking anonymously to discuss the panel's thinking more freely. "One of the things we think the commission has achieved is (that) it set the bar for what action on the deficit means — beyond just symbolic steps."

Members expect that the White House and members of Congress will lean heavily on the bipartisan commission's recommendations, particularly under the divided government that will exist when Republicans assume control of the House of Representatives next year.

"What real-world consequences it will have was never clear because it had to go through the legislative process," Schakowsky said in an interview. "But I think the questions that were raised, the items that were put on the table, the discussion that we've had, the numbers that were developed — I think all of this is constructive going forward."
