The Democrats pulled out one of their most powerful surrogates - and no, it wasn't President [Barack] Obama. Beyoncé showed up at a GOTV rally in Cleveland, joining her husband, Jay Z, and Hillary Clinton.

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.

A big win for [Hillary] Clinton would allow her to claim that the country rejected Trumpism, while a narrow win leaves her limping into office with the highest unfavorable ratings for any new president.

[Donald] Trump's path to victory depends on getting historic levels of support from white voters, and particularly large numbers of white, non-college-educated voters.

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.
