The Numbers After Last Night

Good morning, bean counters! Yesterday, we examined the numbers heading in to last night's primaries. Today, here's where we stand.

There are now just 217 pledged delegates up for grabs for the 6 remaining contests. In fact, for the first time in the race, there are now more undecided superdelegates than there are unallocated pledged delegates.

In terms of the popular vote, a metric used to try and woo superdelegates, Obama nearly erased Clinton's gains in Pennsylvania. With 99% of precincts reporting, he won North Carolina by 232,775 votes while Clinton won Indiana by 22,412. That's a 210,363 net vote gain for Obama. He now leads Clinton by 2.2 million votes.
