Well, I'll put my neck out here.
I think it's because he isn't the same stale, old, white bread politician going for President. He's different, new, a change. If I agreed with his political stance on most things, I'd think he was pretty awesome.
The US hasn't been doing that hot of a job with our current and past leaders in the world view, I think. Being intelligent, fiscally responsible, good at decisions, and strong on stands is all important, but we don't live in an isolationist time, and how countries interact via their leaders is pretty important too. The whole Clinton brouhaha was pathetic and made the White House look like a brothel, and GWB's speaking mistakes sure doesn't make him look like a person to take seriously. Some of his "cowboy" actions have really turned other counties against us, or at least made them choose not to act with us.
Obama looks different that the normal old white guys we usually elect, speaks exceptionally well I've heard, and though one can say his talk of "Change" has no base, it is definately "ear-candy".
I think his travels to other countries is a pretty smart thing - like I said, we aren't isolationists (as much as I would like LOL!) The US has pissed off a LOT of people, a lot of countries. His trips might be sending the message of "Hey, I'm coming to your side, let's talk like equals and work things for the better, together." Extending the olive branch. If that is so, I would be pleased *if* he got elected, to see things come about like other countries bringing jobs HERE to our workforce, seeing the US sign and abide by the Kyoto agreement, and in general work with other countries when it comes to Iraq and other "terrorist" areas.
Other countries have elected women, and I believe other minorities (I can't back that up with what I remember though). In 200+ years, we haven't. That's not to say white men aren't doing an alright job, but there have got to be some good minority leaders out there. Is Obama one? I'm not totally sure.
I still don't know who I'm voting for, probably Libertarian or something, just to cast in the way I feel. I'm just trying to put a post out of *why* Obama is interesting to others. I most likely will not vote for him.
