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.

Donald Trump's staffing up a pretty traditional, very conservative Republican government, not a populist outsider government, at least not yet.

For a long time, many Republicans thought if they just took two aspirin and laid down, [Donald] Trump would go away.

[Mike] Bloomberg aides says he's more likely to run if it's [Donald]Trump or [Ted] Cruz versus Sanders, then there would, presumably, be space in the middle for him. But he's less likely to go if Hillary Clinton is the nominee.

The lesson is that voters in both parties are in a very anti-establishment, populist mood. Hillary Clinton is the establishment candidate.

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.

[Hillary] Clinton has also struggled with key groups of voters.
