If Clinton wins NC, will it be because Repubs voted for her, or will it be because the accumulated weight of Obama's associations pulled him down? Or because people honestly prefer her positions on the issues? Or a combination these and a dozen other factors?
And how can anyone possibly know for sure?
As entertaining as crossover voting is...

... I just don't understand why states allow it. Why on Earth should Republicans get a say in who the Democrats nominate? And conversely, if, say, last winter's received wisdom had prevailed and Hillary had wrapped up the nomination in February, while McCain and Mitt Romney were still duking it out, why would any sane Republican want Democrats sticking their spoons into the pot?
Maybe next year's Super Bowl, New York Giants fans can vote on who the New England Patriots start at quarterback.
