It's hard to imagine a party that is not corrupted by hatred.

Certainly, the country can't have two presidents at once, so the tradition has been to hang back if you're the president-elect and wait for your time in office. [Donald] Trump is not a hang-back kind of guy.

I do think Donald Trump is a fundamentally unstabilizing force and that the people who swore to uphold the Constitution are going to have to take some measures at some point.

Russia has a very sophisticated, advanced attack on U.S. businesses and U.S. government and U.S. institutions. And it's not like Donald Trump is going to be walking away from this. He will be spending a lot of time on it, if he's any sort of normal president.

When you're running for president, you're a guest in the living room for four years. And if people don't think you're going to be around the living room as a pleasant experience, they're not going to vote for you even if they agree with you.

I'm beginning to think [Ted] Cruz had a good convention, that if [Donald] Trump goes down, Cruz is pretty well positioned to be the Republican major figure in four, six or even within two years.

The public is not only shifting from left to right. Every single idea associated with the educated class has grown more unpopular over the past year. . . . A year ago, the Obama supporters were the passionate ones. Now the tea party brigades have all the intensity.
