Republican candidates have won whites with college degrees in every presidential election since polling began.

You have [Donald] Trump and [Ted] Cruz battling it out, and the moderate establishment candidates like Chris Christie or Jeb Bush, Marco Rubio, John Kasich - they have formed a circular firing squad.

The president is under 50 percent approval ratings in all the battleground states. So, you could say that President Obama is defying gravity by still being in a dead heat with Mitt Romney. And one of the reasons that he is, is because the changing face of the electorate are giving him a small boost.

If Pat Toomey of Pennsylvania wins, for instance, it will tell Republicans that their own brand hasn't been hurt too badly by [Donald] Trump's negatives.

While Romney has an overall deficit with women voters, his biggest disadvantage is with college educated women - wherever they work, at home, in an office, a store or a factory.

The establishment is divorcing itself from its base - from voters who are choosing a candidate who says he stands for things that are anathema to the establishment.

Even if [Donald] Trump concedes, some of his supporters have promised to take up arms against [Hillary] Clinton.
