Re: I honestly don't know who'd be worse
You mean even MORE than Obama has managed?
Actually, most people I speak to have seen Obama as a reasonable President. He hasn't gone around starting random wars all over the planet, and has moved international relations forward. Basically, I believe the world's view of the US has improved since he came to office. Admittedly, not by a lot, and it wasn't difficult, but at least he seems to care about both his own people and the rest of the planet.
As far as Trump goes, I fear for the planet with him in control. I don't know whether his persona is real or just a character he portrays, but I do believe he may be the most dangerous man to run for POTUS ever. I can see potential for war and death planet wide if he is elected, and I wouldn't leave him in charge of a chicken sandwich, let alone a nuclear superpower!
