I hope I don't sound opinionated or cause any arguments, but I'd like to share my opinion.
Personally, I think that Trump is a good business man, not a politician or in any state to rule a country. Though he is supposedly a Republican, he said recently "[I'm running against two parties]". Also, Trump is not respectful towards women and ethnic minorities. He has said some very racist things about different races and cultures. Even if Trump does become president, there is not much he can do- if he wants to start a war, he'll have to okay it with Congress. And he cannot make Mexico pay for a wall- the Mexican president said Mexico was in no state to pay for a wall, and even if they were, Mexico wouldn't. Again, sorry if I cause any arguements- this is a tricky topic to discuss, without offending or angering other people.
