I was watching it on MSNBC last night (CNN had the Dummy Debate at the time). Funniest thing ever. Beck had a small crowd around him, Trump walks in, literally almost everyone drops what they are doing to go see Donald Trump.
First, I don't think Trump showing up at the caucus site when Beck was there was intentional. I sincerely doubt the Trump team is tracking Glenn Beck's personal appearance schedule.
However, once he was there, he could have waited until Beck had finished spewing his line of BS, and then entered the caucus room.
Not doing that was a bold and Trumpian choice. It was awesome!
Before they ran to Trump, they started cheering him loudly. I was rolling on the floor as Back first thought they were cheering for him! LOL
