Then there was one: Next-to-last Minnesota superdelegate endorses Obama

The Barack Obama campaign announced Sunday that Nancy Larson (pictured), a member of the Democratic National Committee and one of the last two remaining unaffiliated Minnesota superdelegates, has endorsed Obama. Now only Seventh District US Rep. Collin Peterson remains uncommitted.

Larson is the tenth Minnesota superdelegate to support Obama. The others:  Sen. Amy Klobuchar; Reps. Jim Oberstar, Keith Ellison, Tim Walz, and Betty McCollum; plus Democratic National Committee members Mee Moua, Ken Foxworth, Brian Melendez and Donna Cassutt.

Three Minnesota superdelegates are backing Hillary Clinton: former Vice President Walter Mondale and DNC members Jackie Stevenson and Rick Stafford.

More: Michael Calderone of Politico writes of the discrepancies in news organizations’ tallies of the superdelegate race: “As of April 9, for example, MSNBC reported Clinton had 256 superdelegates in her camp to Obama’s 225. But The New York Times saw a much tighter race: 221 Clinton superdelegates compared with 209 for Obama. Other news organizations tracking superdelegate votes for Clinton and Obama, respectively – including Politico (249-225), CNN (243-215) and The Associated Press (252-224) – also stood at variance with each other.”
