Trump is demonstrably worse on the following issues
1) Climate change and the environment in general- claims global warming is a hoax, and wants to get rid of the EPA (he can't even name it properly. )
2) Education- he wants to get rid of the Department of Education (see above video)
3) Race relations and communal harmony. Has been endorsed by all sorts of fascist and Neo- Nazi groups. Doesn't even have the decency to denounce them.
4) Press freedom- Has threatening introducing libel laws for anyone criticizing him.
5) Gun control- Has flip-flopped a million times on this issue, but has recently come out in support of gun rights and the NRA.
6) Diplomacy- Do you think a man who mocks disabled journalists and questions judges on basis of their ethnicity and wants to ban people from an entire religion will be able to handle tense diplomatic situations? US allies are horrified at the prospect of having him in power while countries like China, Russia and North Korea are encouraging his presidential bid.
7) Economy- The man cannot distinguish between debt and deficit. He is completely clueless about monetary and fiscal policy. He claims he will bring jobs back and make America great again, but has outlined no single policy in order to do so.
I agree with his stance on illegal immigration somewhat, but the solution he offers is impractical, expensive and a waste of time.
The only positive thing about him is that he won't be under the influence of lobbyists (although we will surely try to further his business interests during his time in office.) He is also not an evangelical nut, which makes him a lot better than almost all other Republicans.
Hillary is no saint, and personally I don't like her, but she has the experience and the intelligence to carry out her job with a modicum of competence.
