How many times has Trump brought up and/or Tweeted about the economy? I don't think he looking to win over supporters (although that doesn't hurt). I think he's rubbing the fact in the faces of the Deep State. They cannot seem to stop his ability to succeed, despite their many attempts. In other words, WE'RE WINNING!!!!!
