He couldn't just stay at home alone in the White House where the folks who attended were having fun. He had to go out to draw the crowd to give him love which he never gets enough of and of course it was all about attacking the big bad Dems et al etcetera and so forth. He gets such big kicks out of it. The message is always the same but his audience doesn't mind. They are always thrilled to be there and there in front of him they will always be clapping and cheering and shouting and stomping and high-fiving. What could it hurt, right?
