A week before the North Carolina primary, Senator Hillary Rodham Clinton picked up the endorsement Tuesday of that state's governor, Michael Easley, a man highly popular among the blue-collar white voters who have been a pillar of her support.Easley, a Democratic superdelegate who formerly supported John Edwards, made the announcement - a source of some frustration for Senator Barack Obama's campaign - alongside Clinton in Raleigh. "There's been lots of 'Yes we can, yes we should,' " Easley said, referring to an Obama slogan. "Hillary Clinton is ready to deliver." Obama was also in North Carolina, where he connected with another of the state's most popular symbols, playing basketball with the sky-blue-uniformed members of the University of North Carolina team.
