This year [2016], however, polls show [Hillary] Clinton winning white college-educated voters by double digits.

If they can get 15 or higher, it will be a very bad night for House Speaker Paul Ryan. Ryan twisted himself into a pretzel by endorsing but not always supporting Donald Trump. Now, he's facing the prospect of a slimmer majority, with fewer moderates. Conservative members in the Freedom Caucus have already sent warning shots threatening Ryan's tenure as speaker.

Jeb Bush was supposed to be the establishment candidate, but he didn't catch on. And the extraordinary thing about this Republican primary is that the establishment, moderate wing of the party has sidelined itself. They're not coalescing around one candidate as they have in the past.

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

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

[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.

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