You obviously don’t know HOW TV commercials are made for ANY candidate. Maybe you should avoid eating Sausage because if you saw how it was made you would have a nervous breakdown.
I don’t think it is a question that a commercial may require multiple takes, it is a question as to why the raw unedited footage of the multiple takes was uploaded to YouTube. It makes for some awkward viewing.
I think everyone has learned, in this cycle, that it is a dumb thing to do. The candidate did it to allow others to do commercials without violating the rules about PACs but he didn’t see that people would use the footage to do damaging videos.
