Math, Math, Math

Chuck Todd:

...nearly half of all remaining delegates will get handed out tomorrow. And the math will be a lot more crystal clear after tomorrow, both in delegates and the popular vote. Following Guam, there are now 404 pledged delegates up grabs, and 187 of them will be decided on Tuesday. Plus, per our count, there are 268 undeclared superdelegates. Here are the basics of what each candidate needs: Assuming he wins half of the delegates tomorrow (93), Obama needs just 38% of ALL remaining delegates to get to the magic number of 2,025. If Clinton wins 94 delegates on Tuesday, she will need 66% of all remaining delegates. In addition, assuming that delegate split tomorrow, then Clinton will need 85% of all remaining PLEDGED delegates to catch Obama for the lead in that category. Moreover, if Clinton simply wanted to cut Obama's pledged delegate lead to 100, she'd need to win 62% of all remaining delegates after tomorrow. As we've noted before, the math is certainly difficult for Clinton.
