Ezra Klein, writing for Vox, on the nomination of Donald Trump for President:

He has had plenty of time to prove me, and everyone else, wrong. But he hasn’t. He has not become more responsible or more sober, more decent or more generous, more considered or more informed, more careful or more kind. He has continued to retweet white supremacists, make racist comments, pick unnecessary fights, contradict himself on the stump, and show an almost gleeful disinterest in building a real campaign or learning about policy.

Here is what we know — truly know — about Trump. Here is why he should not be president.

It is downright terrifying that there’s even a chance this man could be President of the United States.
