Let me guess. It’s because we have a black man and a woman, both anti-war to one degree or another, in serious contention for the Presidency, thereby demonstrating that we’re learning to not be such narrow-minded, warmongering imperialists.

Ha! The world is in “Hope-nosis”!
It’s probably more to do with the fact that you are having an election at all - and one that is (and is continuing to be) very closely run. That is forcing an analysis of why by the world’s media, and that is forcing a detailed examination of US politics that is rarely made (particularly domestic issues).
Basically, the profile of the USA is being significantly raised. As some say, there is no such thing as bad publicity!
