Check out the difference between the voters who have already voted and those who are likely to. One explanation could be young people and the other could be a bump from NC and IN. Also more than half the people have already voted.
I think you're mixing up the two columns.
Yeah my bad only 43% of people have voted. But that is so damn close, I really wonder if it is representative. But Obama cleans up among likely voters, I guess the ones who havent mailed theirs yet? This is a weird primary for sure.
