The fact that there is a visual edit right at the same point that if one was misquoting him, there would be an audio edit together is 100% suspicious.
This would never be admissible in court or in a deposition.
Show me a single camera view with the audio this way and I will believe it.
We don’t need to go down deceitful paths, that is the way of the evil one.
I don’t think there’s anything deceitful about the video. He goes on to explain himself afterwards, so obviously he did say it and is trying to correct it.
That said, I don’t think it was an admission of anything. But it does make him look dumb and confused.
Also, I don’t really think this is going to have any impact on his campaign. Heck, even if he came out and said he was a Muslim, I doubt that it would affect his loyalists or, for that matter, most of the country.
