The Obama Nomination Countdown Ends Tuesday Night

Based on the Obama campaign's projection of 38 pledged delegates from Puerto Rico, Montana, and South Dakota, Barack now needs just 27 more superdelegates to secure the nomination on Tuesday night.

And as this report from ABC News suggests, the campaign has no doubt that those superdelegates will come on board:

The Obama campaign is not worried about the tempest that erupted at a Washington, D.C., hotel on Saturday when top Clinton adviser Harold Ickes threatened to take the fight over Michigan's delegates all the way to the convention.

"He said 'reserve the right,' not that he was going to do it," said Obama adviser Anita Dunn. "They have to get through the next three days. I've been there before."

...Asked if Obama would wait to get a concession call from Clinton before claiming the nomination, Dunn said the onus was on Clinton now that the Democratic Party has firmed up the number of delegates needed to claim the party's nod.

"He's not going to wait by the phone like a high-school girl waiting for a date," said Dunn. "That's not Barack Obama."

"After Tuesday," Dunn added, referring to the final contests of South Dakota and Montana, Clinton "can decide how united she wants this party to be."

It all begins in St. Paul at the Xcel Energy Center, site of the 2008 Republican National Convention. We're moving on to the next round.
