I never thought I'd give Donald Trump the benefit of the doubt, so he really better not blow it on this one.

Usually, when Donald Trump steps in political doggy doo-doo by saying or doing something offensive, his response is to double down, build a doggy doo-doo fort, and hang a "No Illegals Allowed In The Doo-Doo Fort" sign on it. But today, his campaign actually deleted a tweet and issued an explanation for the screw-up. That's right, there is a limit to Trump's awfulness: Nazis. Obviously, this is just a screw-up, but's a pretty big screw-up.
