WASHINGTON (November 20, 2009)—U.S. Senate Democratic leaders plan a crucial test vote Saturday on a sweeping health care reform measure, amid indications the rank-and-file will stand together to give them the support they need.

Sen. Dick Durbin of Illinois, the No. 2 Senate Democrat, said Friday that leaders weren't assuming anything and were working to bring the caucus together ahead of Saturday's vote to begin debate on their health overhaul bill.

Two of three moderate holdouts have indicated in recent days that they will vote with fellow Democrats on the procedural vote and Durbin said that the third, Sen. Blanche Lincoln of Arkansas, has informed Majority Leader Harry Reid how she plans to vote.

Durbin wouldn't disclose Lincoln's answer but Democrats are moving ahead with Saturday's vote.

With Republicans united in their opposition, Democrats need the vote of every member of their caucus to reach the 60 votes needed.

The Congressional Budget Office says the $849 billion package would provide coverage to 94 percent of the country while cutting the deficit by $130 billion in the first decade and more after that.

Republicans say the bill will end up costing more like $1.5 trillion and makes no sense.

In fact, Republican objections are so strong that Oklahoma Sen. Tom Coburn threatened to have the entire bill read aloud to delay a vote, but he later backed off.
