The Weekly Standard describes a duplicitous attempt to have it both ways:
The Obama campaign sent out an email today asking supporters to urge Congress to at least vote on the president’s jobs bill almost immediately after Democratic majority leader Harry Reid blocked a vote on the bill in the Senate.
On the Senate floor today, Republican leader Mitch McConnell asked for unanimous consent to proceed on voting on the bill. Reid, who has struggled to find enough votes for the bill in the Democratic caucus, objected to the motion and killed the opportunity for a vote....
Democratic members of Congress are aware of the toxic nature of Obama's jobs bill (and how the current President will hang them out to dry if anything goes wrong), so some conservatives are trying to call their bluff by pushing for passage of this drain on the public treasury.
