I keep hearing his name being banded about in the US Election but aside from knowing he's a Republican candiate, I know next to nothing about him.

A lot of people seem to think he's one of the better Republican candidates but I'm not really sure "better" from who's perspective.

Basically I'm interested to know whether, in the unlikely event he were the Republican final candidate would this be a good thing or a bad thing for the world in geneeral?
