After months and months at the top of the polls, there is a real possibility that Donald Trump could be the nominee.

[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.

If [Hillary] Clinton wins, history will also be made: She would be the first female U.S. president, of course, but also the only candidate in the modern era, other than George H.W. Bush, who managed to follow a two-term president of her own party.

There was another Cleveland rally [of Hillary Clinton] - this one with LeBron James.

The GOP establishment, in particular, is facing a pick-your-poison kind of decision. Many establishment Republicans dislike [Ted] Cruz personally. He has no Senate endorsements.

As one person said to me , Republicans know [Donald] Trump is a stain on their party.

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.
