Democrats are using the nuclear option to try to ram their government takeover of health care through the Senate. The fate of that legislation may come down to a dozen or so members of the House of Representatives opposed to government-funded abortions. Right now, the vote in the House couldn't be more closely divided.

The original version of the bill passed the House in November by a narrow 220 to 215 margin. Since then, three Democratic supporters have left Congress through retirement or death. A fourth, Rep. Eric Massa, New York Democrat, is reportedly resigning today because of charges that he sexually harassed a junior male staffer. The lone Republican who supported the bill has seen the light and switched his vote. All told, if no one else switches votes, the vote count stands at215 in favor and 216 against.

Intrade - the prediction markets that have proved so accurate in forecasting everything from election outcomes to who is going to win "American Idol" - shows that as of Friday morning, the odds of the health takeover getting passed are about 50-50.
