More: Vernice Sack, 80, and her husband, Paul Sack, 83, counted themselves among the first-time caucusgoers. They both supported Mr. Obama, they said. “He’s got the right ideas,” Mr. Sack said.

In a typical display of arrogance: The campaign now moves to Mississippi, which holds its primary Tuesday. Mr. Clinton campaigned there Saturday, striking a theme his wife has been repeating on the campaign trail: that Mr. Obama would make a good running mate (but as second fiddle.)

Pretty brassy for someone behind in the delegate count and nearly mathematically impossible of overtaking Obama in delegates.
