KidKilobyte: “Just saw this on his twitter feed and got a pit in my stomach. How can his base tolerate such bad timing and bad taste in what he posts? Other than fringe lunatics, what do educated Trump supporters say about his constant stream of garbage. Why does goosing the economy trump (pun intended) good taste and excuse such an unrelenting stream of garbage from his mouth? And as to the “great” economy, seems the deficit is ballooning and this train is headed for a bridge that is out.”
