Rep. Roy Blunt, R-Mo., the whip, estimated that Pelosi's speech changed the minds of a dozen Republicans who might otherwise have supported the plan.
Frank said that was a remarkable accusation by Republicans against Republicans: "Because somebody hurt their feelings, they decided to punish the country."
The presidential candidates kept close track - from afar.
In Colorado, Democrat Barack Obama said, "Democrats, Republicans, step up to the plate, get it done."
Republican John McCain spoke with Treasury Secretary Henry Paulson and Federal Reserve Chairman Ben Bernanke before leaving Ohio for a campaign stop in Iowa, a spokeswoman said.
Monday's action had been preceded by unusually aggressive White House lobbying, and Fratto said that Bush had been making calls to lawmakers until shortly before the vote.
Bush and his economic advisers, as well as congressional leaders in both parties had argued the plan was vital to insulating ordinary Americans from the effects of Wall Street's bad bets. The version that was up for vote Monday was the product of marathon closed-door negotiations on Capitol Hill over the weekend.
"We're all worried about losing our jobs," Rep. Paul Ryan, R-Wis., declared in an impassioned speech in support of the bill before the vote. "Most of us say, 'I want this thing to pass, but I want you to vote for it - not me.' "
With their dire warnings of impending economic doom and their sweeping request for unprecedented sums of money and authority to bail out cash-starved financial firms, Bush and his economic chiefs have focused the attention of world markets on Congress, Ryan added.
"We're in this moment, and if we fail to do the right thing, Heaven help us," he said.
The legislation the administration promoted would have allowed the government to buy bad mortgages and other rotten assets held by troubled banks and financial institutions. Getting those debts off their books should bolster those companies' balance sheets, making them more inclined to lend and easing one of the biggest choke points in the credit crisis. If the plan worked, the thinking went, it would help lift a major weight off the national economy that is already sputtering.
More than a repudiation of Democrats, Frank said, Republicans' refusal to vote for the bailout was a rejection of their own president.
