Americans like to give their President the benefit of the doubt. If you look at the poll numbers, people knew Nixon was deeply involved in Watergate and stayed with him for a long time. It's a natural tendency.

Trump hasn't really done anything yet to abuse his powers. I don't even know if he knows what all his powers are as president. And that worries me. He will learn. After he learns how the presidency works, he could become much more dangerous, because his personality doesn't change. Once presidents find their powers, they don't give them up. They use them.

I don't think Trump is a deeply self-aware person. But he's absolutely off the charts as a narcissist. He is the consummate narcissistic salesman. He is in fact a sick man. And that's potentially very dangerous. The only positive thing about Trump is that he has no ideology, he is an empty vessel, surrounded by people who give him ideas, and it only matters which ideas will shine the light on Trump.

Who voted for Trump? Who are these people who, as he famously said, would let him shoot someone on Fifth Avenue and still support him? It's people who want too strong a leader, who would do what that leader tells them. Similar to the Europeans following Mussolini and Hitler. There's a streak in humanity that likes that kind of leader. That's Trump's core. Authoritarianism.

There's a political reality about impeachment. It's purely a political process. The interpretation of "high crimes and misdemeanors" can reach a long way, all the way to sex in the Oval Office, which was an absurd use of the impeachment clause.

One of the reasons I thought a censure resolution was appropriate was because if somebody had censured Nixon or even if a resolution of either house had passed, saying what you're doing is unacceptable to Congress, that shot across the bow might have straightened him up.

There are similiarities between Nixon and Trump, no question. But there are also big differences. Nixon was shy, private, he attacked the media behind closed doors and insulted people behind their backs, and we only know about it because of the taping system in the Oval Office. The dark side, the vengeance we only know because of these tapes. Trump is right out and front with it. He actually campaigned on how nasty he can be, which found resonance with enough voters to get him into the White House.
