More superdelegate news: Obama gains another...Bloomberg: Obama Cuts Into Clinton's Delegate Lead Among Elected Officials

Today the Obama campaign announced another superdelegate commitment, Melissa Schroeder (DNC-WI) , Wisconsin’s 7th District Democratic Party Secretary citing his [Obama's] unique ability to stand up to the special interests and unite all Americans to bring about real, meaningful change.

Melissa Schroeder said: “After much consideration, I have decided to endorse Senator Barack Obama. My decision came down to electability and who I felt would do a better job of unifying this country for a common purpose. Obama’s message of hope and change has touched millions of voters in a way that I haven’t seen since the late 1960’s. People from every walk of life, young and the not so young, Democrats, Independents and some Republicans, are all rallying around a belief that change can happen if we want it bad enough. With Obama as our nominee, I am confident that this November we will increase our majority in the House and Senate and elect a Democrat to the White House.”

Bloomberg.com reports that Obama is almost even to Clinton in endorsements from top-elected party officials and has cut into her lead among the other superdelegates, which she's counting on to win the nomination.

Among the 313 of 796 superdelegates who are members of Congress or governors, Clinton has commitments from 103 and Obama is backed by 96, according to lists supplied by the campaigns. Fifty-three of Obama's endorsements have come since he won the Jan. 3 Iowa caucuses, compared with 12 who have aligned with Clinton since then.

"That's not glacial, that is a remarkable momentum,'' Senator Claire McCaskill of Missouri, a superdelegate and Obama supporter, said in an interview. "I don't think there is anything that will slow that down.''

Democratic elected officials have the most at stake in the nomination because the candidate at the top of the ticket in November will have an impact on state and local races.

In the overall race for superdelegates -- elected and party officials who automatically receive votes at the Democratic National Convention that will choose the nominee -- Clinton leads Obama in commitments by 249 to 212, according to an Associated Press tally.
