A few hours after Rep. Dennis Kucinich switched his support to become a critical vote for the health care bill, he took to the House floor to ask wavering colleagues to join him. Astonished colleagues pointed to Kucinich (D-OH) darting from member to member on the House floor yesterday, saying privately they'd never seen him get so involved in whipping a vote.One thing you can say about Kucinich. When he's in, he's all in.It's not just progressives he's targeting to keep in the fold, it's everyone, a top Democratic aide told me. Members know that Kucinich - a staunch antiwar liberal long in favor of a single-payer system and often going out on a limb with his own agenda - is setting aside deep ideology to help get something passed. "It's a totally new dynamic. People are realizing he's doing it for history," the aide said.
