Everything on Twitter is true.

American democracy faces a massive challenge. I don't think it is a certainty that we're headed toward Putin's Russia, as some commentariat does. But people need to mobilize and build up small-d democratic institutions to prepare against that eventuality.

Barack Obama is a very impressive human being.

Trump is what Obama critics think Obama is: Someone who's focused on symbolism rather than substance.

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.

I'm convinced in 100 years Obama will have an important place in the civic pantheon of American life.

On Obamacare, every day that goes by I have more evidence that I wish I could put in my book, on how difficult it is for the Republicans to eliminate this law. They have no real alternative. They're afraid to take away health care from the 20 million people who now have it.
