I like your idea, but he has done rallies for the primaries and the general, and has given speeches where he has been invited. The speeches usually are almost exactly the same if the events are close, but with some ad-lib that is for the locals. Honestly if he is treating them like a weekly address he needs to do better. I watch most of them and it does get old hearing the same stuff all the time (minus local and/or recent topical stuff). I wish he would mix them up more, but I also get that not everyone watches all of them.

I bet the RSBN guys can almost recite them verbatim by now. They're still better than most stuff on TV though.
