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.

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.

What does [Hillary] Clinton do if she loses? Concede? Blame the Russians? Or the FBI?

Hillary Clinton is also not a very exciting, inspiring candidate to a lot of the left-leaning Democratic base, especially in Iowa.

Meanwhile, there are some traditional battleground states - like Ohio and Iowa - that are becoming older, whiter and less educated. That's turning them from true battlegrounds into more reliable red states.

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.

For Democrats, anything less than 15 net pickups will be a disappointing outcome [in presidency race].
