*** The new math: Another thing that last night did was kill the Clinton’s campaign’s two best talking points. First, the popular vote: After last night, Obama now leads Clinton by more than 700,000 (16,050,924 vs. 15,336,896). When you include Florida, Obama leads by 419,256, and when you include both Florida and Michigan (and don’t give Obama “uncommitted”), his lead is 90,947. And here’s what’s left in our pop vote simulator
Total votes Clinton Obama Split
WV: 400,000 240,000 160,000 60-40
KY: 500,000 300,000 200,000 60-40
OR: 600,000 270,000 330,000 45-55
SD: 100,000 45,000 55,000 45-55
MT: 125,000 56,250 68,750 45-55
Totals 911,250 813,750
Under this scenario, Clinton will net 97,500 in the remaining contests. So Clinton can win the popular vote if you count Florida and Michigan, but it’ll be close and it’s just as likely with a bigger than expected win for Obama in Oregon that he can actually win the popular vote even with netting ZERO votes out of Michigan. This shows just how massive both turnout was in North Carolina and the margin of Obama’s victory was in the state. Once again, he shows that when he wins a state, he wins big.
Clinton has only won 60 or more percent of the vote in one state, Arkansas with 70% of the vote.

This vote simulator forgets Puerto Rico.
The Clinton camp is dreaming of a 600,000 Clinton vote advantage in PR. 350,000 may be more realistic, but PR will at least close the popular vote count.
