Personally, I actually do think that Trump didn't mean to mean what he said and I do buy that what he was supposed to say, "but second amendment people, you can do something about that by electing me" which was garbled because he is an unscripted moron.
But here's the thing, all Trump has to do is say "I misspoke, I meant to say _______, I do not condone any violence against Hillary Clinton" (see that Trump, you didn't even have to apologize!) but he refuses to admit that he makes ANY mistakes. Instead we're just treated to a week-long press cycle where the press goes after him, his surrogates put out a bunch of different and conflicting defenses, and all he does is deny deny deny and yell at people on twitter.
If you meant
"supposed to say, but mouth said the opposite of what brain thought", then maybe. However, Trump's words were implying
after she was elected. This has been gone over quite a bit in the news now. I think the more plausible "pro-Trump" explanation here is that he meant exactly what the media is saying, except that he didn't think it was a big deal and wasn't joking, but wasn't really serious either. In other words, he just said whatever crap came to mind and then moved on, as he usually does. This is Trump's M.O. - He just says whatever pops into his head.
