You're right, the numbers are quite possibly higher. I can't imagine someone who answered an exit poll saying they voted for a primary candidate they would not support in the general election were being anything less then honest because it's quite frankly a strange assertion to make. The analysis I did is of course bound by any margin of error in the exit poll.

I get your larger point about delegitimizing her win, though you also have to realize frustration among Obama supporters when what likely would have been a win for them was taken away. The Obama campaign has had a brutal time the last two months and a double win would have been a huge development. I still believe it's important to understand what happened as an argument to the superdelegates if nothing else.
