"You know, I think there are a lot of superdelegates who are waiting for the last couple of contests, but I think that they're going to be making decisions fairly quickly after that," Obama told reporters in Waterford, Mich. "My sense is between Tuesday and Wednesday we have a good chance of getting the number that we need to achieve the nomination."
Maryland's Sen. Benjamin L. Cardin joined a handful of Democratic senators who are undeclared superdelegates at a meeting in Washington yesterday.
"There wasn't really any outcome," said Cardin spokeswoman Sue Walitsky, who characterized the meeting as "a chance to get caught up on where things are" regarding the presidential race.
She said Cardin "has not made any decision with regards to timing" of his announcement.
Other senators attending the meeting included Tom Harkin of Iowa and Ken Salazar of Colorado, CNN and the Associated Press reported.
"A lot of us just feel that the sooner this is sort of put to bed, the sooner we have a nominee, the better off everyone's going to be," Harkin said.
Bob Mulholland, a California superdelegate and DNC member, said the Obama campaign contacted him last week with a new pitch.
"The message was, 'Wouldn't you like to be one of the last'" superdelegates to put Obama over the top, he said.
