Why should Democrats change the playbook, when the current one works so well?

Florida in 2000. Washington state in 2004. Minnesota in 2008. Keep recounting until the Democrat has a decent lead, then shut down the process.

The Wall Street Journal, January 4:

Strange things keep happening in Minnesota, where the disputed recount in the Senate race between Norm Coleman and Al Franken may be nearing a dubious outcome. Thanks to the machinations of Democratic Secretary of State Mark Ritchie and a meek state Canvassing Board, Mr. Franken may emerge as an illegitimate victor.

Mr. Franken started the recount 215 votes behind Senator Coleman, but he now claims a 225-vote lead and suddenly the man who was insisting on "counting every vote" wants to shut the process down. He's getting help from Mr. Ritchie and his four fellow Canvassing Board members, who have delivered inconsistent rulings and are ignoring glaring problems with the tallies.

Minnesotans like to think that their state isn't like New Jersey or Louisiana, and typically it isn't. But we can't recall a similar recount involving optical scanning machines that has changed so many votes, and in which nearly every crucial decision worked to the advantage of the same candidate. The Coleman campaign clearly misjudged the politics here, and the apparent willingness of a partisan like Mr. Ritchie to help his preferred candidate, Mr. Franken. If the Canvassing Board certifies Mr. Franken as the winner based on the current count, it will be anointing a tainted and undeserving Senator.
