So the delegate split in Mississippi is tentatively set at 19-14 Obama, a +5 advantage. Obama could've gotten an extra delegate had he won the at-large vote, minus non-viable candidates (those under 15 percent), by 62.5 percent.
The viable candidate current results, with 100 percent reporting:
Obama 255,809
Clinton 155,686
Assuming there aren't any provisional or absentee ballots still hanging out there, waiting to be added to the final certified count, Obama's percentage of that vote will be 62.165761. Oh, so close. The Rush Limbaugh vote successfully denied Obama a two-delegate swing.
p.s. I suck at math, so please double-check it.
Update: People in the comments are acting as if I'm "decrying" the Limbaugh vote. I'm not. We tried it in Michigan. If he can cause mischief in our contests, all the power to him.
