Dems schedule unpopular Obamacare vote for dead of night

The Senate version of the Democrats' so-called health care reform is so unpopular,  Nevada's Harry Reid finds it necessary to vote on it at 1:00 a.m.

David M. Herszenhorn reports the Democrats must conduct six votes to pass their Obamacare -- one of the crown jewels of Obamaism:

• 1 a.m. MONDAY – To end debate on “a manager’s package” that includes all the latest changes to the bill. 60 votes required.
• 7 a.m. TUESDAY – To approve the manager’s package. Simple majority required. 
• Also TUESDAY – To end debate on Mr. Reid’s original health care proposal, as amended by the manager’s package. 60 votes required.
• 1 p.m. WEDNESDAY – To approve Mr. Reid’s original proposal. Simple majority required. 
• Also WEDNESDAY – To end debate on the finalized health care legislation. 60 votes required. 
• 7 p.m. THURSDAY, Christmas Eve (or anytime after the prior vote if all senators agree) – To approve the final bill. Simple majority required. 

The legislation the Democrats are rushing through the Senate has yet to be revealed, so vote the Democrats scheduled for the middle of the night will come less than 40 hours after it is made available -- well short of the 72 hours Democrats promised the bill would be available before any vote:

The Senator mentioned, I note, having in mind the managers' amendment, which he has not seen and, frankly, this Senator has not seen either. I have some ideas what is in it, but I have not seen it myself. I think as a practical matter this will be available for 72 hours, as the Senator suggests. Why do I say that? I say that because it is my expectation that Senator Reid's managers' amendment will be filed very quickly, maybe in a day or two [emphasis added].

What are the Democrats trying to hide?
