The blogosphere has crossed the partisan divide by uniting in the effort to unmask the senator who has a "secret hold" on the Coburn/Obama bill that would create a searchable database of pork projects.  A deluge of calls to Senate offices has yielded scores of denials while bloggers speculate about who the culprit might be.  The cyberspace campaign has meant terrific publicity for the popular measure.   The "Parlor Game Publicity" thrills the bill's Senate supporters.  In fact, "secret holds" aren't all that secret, within 72 hours the Senate leader reveals who the senator is to the bill's sponsor.  People in the know know who has this hold and expect it to be publicly known soon.  And conservatives know how valuable these holds can be.  Many senators have blocked many bad things by putting a hold on legislation — although this time it might be more personal animus than policy dispute.
