I'm going to start off and say that Trumps supporters love him based on the simple fact that he gets shit down and he's fulfilling the promises that he made to them, this is something that they believed in and they wanted. They wanted change and that's what he's giving them.
People will like him until the effects of the changes are felt. Deregulation. Maybe another economic crash. More corruption. Even worse education. Worse healthcare. Etc.
Trump is the grenade that the middle class is throwing into Washington and they're going to see change, immense change.
But i doubt it's going to be change the middle class likes. Much less the poor.
