I would agree that he doesn't care about anything but his own agenda. But we have to face the fact that his actions play right into the desires, fears and frustrations of a large demographic of Americans. Thats what he needs to do to keep his support happy
I doubt he gives a flying foo about a wall. He is their super hero because he is giving them what they think they want. Just an act imo. Any real and smart politician would listen to the opinions of ALL Americans not specific groups. But I guess said politician would have to give a fuck about all American people and not just the ones that will keep them in office.. vant think of many on either side that fit that description...
