Barack Obama is extremely smart.

Donald Trump will be a tragedy, a sad joke in American history.

There's an element of clowning and entertainment to Trump, that makes it surreal and hard to understand to what extent he is pretending to be a fascist or an authoritarian.

Barack Obama knows a lot about a lot of things.

That's an important Obama accomplishment: he raised taxes back to Bill Clinton levels, and made a major dent in inequality doing so. That's certain to be reversed, that's going to disappear. The Republicans are going to slash the rich's taxes.

The story of the Republican Party is of a far-right that has moved from the fringes of the party to a complete domination of the party. The moderate, mainstream and pragmatic leaders of the party have been pushed out or died off.

Activists measure progress against the standard of perfection, or at least the most perfect possible choice. Historians gauge progress against what came before it.
