Jonathan Weisman has a fascinating, even riveting narrative of what went down in Washington on Thursday as John McCain made his play to commandeer the high-level negotiations over the bailout bill. And TPM Reader TW called my attention to a passage that may help to explain the smoldering hostility that made it impossible for McCain even to make eye contact with Barack Obama during last night’s debate.

We pick up Weisman in that big meeting at the White House …

Pelosi said Obama would speak for the Democrats. Though later he would pepper Paulson with questions, according to a Republican in the room, his initial point was brief: “We’ve got to get something done.”

Bush turned to McCain, who joked, “The longer I am around here, the more I respect seniority.” McCain then turned to Boehner and Senate Minority Leader Mitch McConnell (R-Ky.) to speak first.

Boehner was blunt. The plan Paulson laid out would not win the support of the vast majority of House Republicans. It had been improved on the edges, with an oversight board and caps on the compensation of participating executives. But it had to be changed at the core. He did not mention the insurance alternative, but Democrats did. Rep. Barney Frank (D-Mass.), chairman of the House Financial Services Committee, pressed Boehner hard, asking him if he really intended to scrap the deal and start again.

No, Boehner replied, he just wanted his members to have a voice. Obama then jumped in to turn the question on his rival: “What do you think of the [insurance] plan, John?” he asked repeatedly. McCain did not answer.

One Republican in the room said it was clear that the Democrats came into the meeting with a “game plan” aimed at forcing McCain to choose between the administration and House Republicans. “They had taken McCain’s request for a meeting and trumped it,” said this source.

Congressional aides from both parties were standing in the lobby of the West Wing, unaware of the discord inside the Cabinet room, when McCain emerged alone, shook the hands of the Marines at the door and left. The aides were baffled. The plan had been for a bipartisan appearance before the media, featuring McCain, Obama and at least a firm statement in favor of intervention. Now, one of the leading men was gone.
