One of Minnesota's last uncommitted Democratic superdelegates has announced she is supporting Barack Obama for president.
Democratic National Committee member Nancy Larson of Dassel said she decided to support Obama, because she believes he's got the best chance of winning in the general election.
But Larson said it was a difficult choice.
"I just think they are both wonderful candidates. Its been really difficult for me to make up my mind," Larson said. "But I think the thing that really swung me over to Obama was his wonderful grassroots type of campaigning and the number of people he's got helping him out and supporting him."
Larson said she previously considered endorsing Hillary Clinton.
Larson joins eight other Minnesota superdelegates who are supporting Obama.
Three are backing Clinton.
Larson's announcement leaves U.S. Rep. Collin Peterson as the only remaining uncommitted superdelegate from the state.
