Also, one more thing we noticed. There was a camera man following along with the president and also during the speech taking pictures of the crowd. We theorized this was so they could study them to see if maybe the same people were showing up to different venues, like stalking or something.
On a different note, before the President's speech at the RNC, when Fred Thompson was speaking, there was a picture of the President hugging a little girl. That was at Lebanon, Ohio, right in front of us. It was a day I will never forget. I was trully honored!
BTW, if anyone thinks this was too much info, like loose lips stuff, feel free to pull my post, I won't be offended.
I'd say it's a good bet your theory is correct. I've heard from a family who has a son-in-law SS that an unbelievable amount of prep work takes place for each and every appearance the President makes. IMO, they just can't be paid enough for the job they do.
