In every interview he does, Barack Obama insists that the primary is not over and that Senator Clinton is still a formidable opponent.
But his actions suggest he is moving on to the general election. He's already launched a 50-state voter registration drive. Today he's campaigning in the general election battleground of Missouri. Tomorrow, Michigan. Next week, Florida. His general election tour effectively starts this week.
Hillary Clinton is going to win West Virginia today by 25-35 points. She'll likely win Kentucky one week from today by the same margin. In his speech tonight and his speech next Tuesday, look for Barack Obama to make only a perfunctory recognition of the results and then use the spotlight to make his general election pitch.
He won't say that the primary is over. The media will say that for him.
Update: Oh, and they're staffing up.
