Don't let the appearance of him being the lovable oaf fool you, Bush was just as bad with his illegal war that he dragged Britain into and caused the Labour to be hugely unpopular.
Trump sucks, but he hasn't pushed us in two wars and had a huge recession yet.
Things that Trump has done that just as bad if not worse;
-Threaten North Korea into a nuclear war,
-Working hard to reverse the affordable health act,
-Discrediting the news media by spouting "fake news",
-Empowered the rise of Neo Nazi,
-Straight up refuse to help Puerto Rico even going to insult the Mayor,
-Banned Muslim from entering the US,
Trump is already on this way causing unfolded damage, which will take years to repair.
