Campaigns are fun. Campaigns are police escorts, they're airplanes, they're crowds, they're balloons, they're bands, a lot of fun. You speak in vague generalities. You get applause for slogans. And then governing comes. And governing is tedious and it's difficult an it's time-consuming and it demands your attention. And policy isn't vague generalities. It's specifics and it's based on knowledge.

I do think, over the last years, a lot of Republicans have decided it's not working, what the party believed in, free trade, global capitalism, open borders.

President [John F.] Kennedy, after the Bay of Pigs, said to Turner Catledge of The New York Times: I wish you had written more, I wish you had investigated more, because it might have saved the country of the cataclysm of the Bay of Pigs.

Mitt Romney was the man who stood up to Donald Trump early, hard, never wavered.

Something really serious has shifted in the minds of Republicans and certainly others.

For many years, we have had these campaign finance reforms, and they have been failures. Money is more coursing through our system than ever before. Incumbents have used the laws to advantage themselves. And one of the reasons I think they have been failures is we have tried to crush down the money in places like the political parties, and it has squished out into opaque super PACs and sort of hidden channels.

Donald Trump, I hate to tell people who are concerned about it, is not going to be impeached. The American people believe in giving somebody a fair chance. He's a new president. There have been troubles, there have been problems.
