The Senate just voted down a resolution that would have prevented Barack Obama from tapping the remaining $350 billion of the financial bailout. The final vote was 42-52, and there were vote-switchers galore since the chamber last agreed to give a boatload of cash to George Bush's Treasury Department.

Democratic Sens. Russ Feingold (WI), Bill Nelson (D-FL), Maria Cantwell (WA), Byron Dorgan (ND) and Ron Wyden (OR), in addition to Sen. Bernie Sanders (I-VT), stuck to the same anti-bailout stances they took in October.

Sens. Claire McCaskill (D-MO) and Mary Landrieu (LA), both of whom voted against giving Bush the first half of the financial rescue money, decided to give Obama the money this time. McCaskill had been particularly skeptical of Bailout Part Deux earlier this week.

Sens. Blanche Lincoln (D-AR) and Evan Bayh (D-IN) switched from affirmative votes under Bush to disapproval of the bailout under Obama. Flexing their rebellious muscles as centrists, perhaps?

Among Republicans, Sen. Susan Collins voted against the new cash while Olympia Snowe sided with Obama -- a rare moment of difference for the Maine moderates. Sen. John McCain (R-AZ), reversing his always-awkward campaign-trail support for the bailout, voted to disapprove it today. And Sen. George Voinovich (R-OH), on his way to retirement, bucked today's party line to okay the cash for Obama. (As Ben Smith notes, this is only the beginning of the campaign to bring Voinovich on board Obama's economic plan.)
