That's not a slogan, and you're comparing apples to oranges, you know there's a big difference in what Obama thought and the catchy things Trump says, "Crooked Hillary", "Low energy Jeb", "Little Marco", "Fake news", "It's a hoax", "Rocket man", "Shithole countries", "No collusion", he speaks on a 4th grade level, this has been proven, and his fans don't care how ignorant he is, the just love it when he says he's building a wall and shouts who's going to pay for it? And the crowd yells back "Mexico". His fans aren't interested in any fact based speech, they just love the catchy phrases
