Undated (AP) An aide for Barack Obama says campaign staff woke up today feeling good, aware that the support of superdelegates over the next day or so will clinch the nomination.
Tonight, Obama hosts his primary wrap-up rally in the same St. Paul, Minnesota arena where republicans will gather for their convention in September.
Obama said yesterday that a number of superdelegates have already privately pledged support, but are waiting for the Democratic Primary calendar to end. That happens tonight when the polls close in South Dakota and Montana.
Hillary Rodham Clinton's wrap-up party is in New York, and memos sent to staffers suggest that's also where her run for the presidency will stop. But the campaign has put out mixed signals about whether she'll concede the nomination.
John McCain campaigns in louisiana. He'll give a speech in the New Orleans suburb of Kenner, hoping to contrast himself to Obama on the issue of bringing change to Washington.
