Eric Kleefeld crunches the Michigan numbers at TPM Election Central and arrives at a similar conclusion to what Hillary's Michigan co-chair conceded to us yesterday: a re-vote there is likely to have minimal impact on the overall delegate race.

But clearly the Hillary people know this, so why all the effort from them to make a Michigan re-vote happen?

It all goes back to their last-ditch strategy to pull out the nomination by making Obama seem, between now and the convention, unelectable in a general election. And there is probably no better way to do that than by running off a string of victories in the remaining states, especially in a big state like Michigan.

Their goal is to put superdelegates in the position that the NCAA tourney selection committee faces each March: Who deserves to be in the big dance more -- the team with the better overall record on a late season losing streak or the one who started the season slow and is finishing on a roll.
