Nov. 21 (Bloomberg) -- Senate Majority Leader Harry Reid tonight faces the first big test of whether he can keep his Democratic colleagues united behind health-care legislation.

Senators plan to take a vote at 8 p.m. Washington time that would clear the way for debate on the most sweeping changes to the U.S. health system since the 1965 creation of the Medicare program for the elderly and disabled.

With every Senate Republican opposing the legislation, Reid can’t afford a single defection from his 60-member caucus to enable the chamber to take up the bill when Congress returns from a weeklong Thanksgiving recess. By late yesterday, Democrats had locked up almost all the votes they needed.

“We’re not assuming a thing,” Illinois Senator Dick Durbin, the No. 2 Senate Democrat, told reporters. “We’re working hard to bring all Democrats together.”
