Both Indiana and North Carolina, the next two states, allow independents to vote in Democratic primaries, and North Carolina has a decidedly young population (it is here that the Pennsylvanian youths moved!). Obama should win both of these states, North Carolina by a lot, Indiana by a little, and their combined effect should wipe out most of the gains Hillary got from her Pennsylvania win.
By the time the voting ends on June 3, Obama will still lead Hillary among elected delegates by 100 to 150 delegates.
At that point, the Gang of Four — Gore, Edwards, Pelosi and Dean — will probably call on the superdelegates to make commitments in the next 10 days so that the race can draw to a close and the party can have its nominee. Shortly thereafter, Obama will be able to claim that he is above 2,025, the threshold for victory. And the ref will be raising his arm in triumph.
