Actually, I think we all understand just fine why Donald Trump is president: because he ran a racist, boorish, epically mendacious campaign and Republicans all decided to go along with it. And even that wouldn’t have been enough if Trump hadn’t gotten some additional help from his pals James Comey and Vladimir Putin.

Donald Trump lied about criticizing Mark Zuckerberg.Ben Carson lied about Mannatech.Carli Fiorina lied about the size of the tax code.Marco Rubio flatly refused to answer a question ("discredited attacks from Democrats") that I guess he didn't think he could just lie about. This is quite a debate.

[David] Muir tried four or five times to get a straight answer about [Donald] Trump's idiotic claim that 3-5 million noncitizens voted, and Trump just flatly wouldn't engage.

If Democrats vote against everyone sight unseen, then Republicans will vote for everyone sight unseen. However, if Democrats demonstrate that they’re considering each candidate on the merits, they have at least a fighting chance of defeating one or two of Trump’s nominees.

I watch CNN, it's so much anger and hatred and just the hatred.

I don't support everything Bernie Sanders supports, but I support most of it: universal health care, reining in Wall Street, fighting climate change, reversing the growth of income inequality, and so forth. If we could accomplish all this in a couple of years, I'd be delighted. But we can't.

If you want to make a difference in America, you need to be prepared for a very long, very frustrating slog.
