"We could have gotten there today had it not been for the partisan speech that the speaker gave on the floor of the House," Boehner said.

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.

That amounted to an appalling accusation by Republicans against Republicans, said Rep. Barney Frank, D-Mass., chairman of the Financial Services Committee: "Because somebody hurt their feelings, they decide to punish the country."

More than a repudiation of Democrats, Frank said, Republicans' refusal to vote for the bailout was a rejection of their own president.

Indeed, many GOP lawmakers spurned Bush's urgent calls for action. "We have a gun to our head," said Rep. Ginny Brown-Waite, R-Fla., who opposed the bill. "This isn't legislation — it's extortion."

The two men campaigning to replace Bush watched the situation closely — from afar — and demanded action.

In Iowa, Republican John McCain said his rival Barack Obama and congressional Democrats "infused unnecessary partisanship into the process. Now is not the time to fix the blame; it's time to fix the problem."

Obama said, "Democrats, Republicans, step up to the plate, get it done."

Lawmakers were under extraordinary pressure from powerful outside groups, which gave notice they considered the legislation a "key vote."

The U.S. Chamber of Commerce said opponents of the bailout would pay for their stance.

"Make no mistake: When the aftermath of congressional inaction becomes clear, Americans will not tolerate those who stood by and let the calamity happen," said R. Bruce Josten, the Chamber's top lobbyist, in a letter to members.

The conservative Club for Growth made a similar threat to supporters of the bailout.

"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."'

"We're in this moment, and if we fail to do the right thing, Heaven help us," he said. If Congress doesn't come around on a bailout, more pressure would fall on the Federal Reserve.

The Fed, which has been providing billions in short-term loans to squeezed banks to help them overcome credit stresses, could keep expanding those loans to encourage lending. And, it could keep working with other central banks to inject billions into financial markets overseas.

It also has the power to expand emergency lending to other types of companies and even to individuals if they are unable to secure adequate credit.
