It's usually before. Stroke a big check to whatever candidate he's there for and you'll get quick intro and a picture.
I got to do the same thing a few weeks ago. It was pretty bad ass.
Wore a Q lapel pin, I watched closely if President Trump saw it, he did. His whole demeanor changed, for the better, we went from being a good looking couple to a beautiful couple when he saw it. He gave me a stern slap and squeeze on the shoulder. I didn't say much, I froze, he is very friendly and approachable but still one hell of a presence. It was an incredible experience.
Can confirm, this is the same thing that happened to us. We ended up in front of the President.
Rush, Hannity, and Savage drop crumbs and hints.
Beto is a racist.
