Trump's coalition becomes more broadbased

A couple of months ago, the conventional wisdom was that Donald Trump was banking on the support of white working class voters. And, tonight, he certainly did well with the non-college population; he overwhelmingly won their support.

But early exit polls also suggest the business man-turned politician has built a much broader coalition. In Massachusetts, a majority of GOP primary voters had a college degree. And, Trump seems to have won college grads overwhelmingly. Early exit polls show he had 45 percent to Ohio governor John Kasich's 21 percent and Florida Senator Marco Rubio's 19 percent. The three of them were in a virtual tie among post-graduates. Keep in mind, of course, we don't have the margin of error for these polls.

In Alabama, Georgia, and Tennessee it was a similar story. Trump won college grads. The picture is more complicated in Texas, Oklahoma, Virginia, and Arkansas. But the exit polls suggest even if Trump did not win college voters, he came close. And, the results debunk the idea that Trump has a ceiling limited to white working class voters.
