Interesting. The US only poll has a more even split between Obama and McCain. The rest of world poll has almost no McCain support. Interesting!
I lived in Europe for a few years, well before I'd really ever even gotten into politics. Basically all I got were tidbits of the pop-culture opinions on things. Towards the end of my stay, the whole '04 election Bush vs Kerry was going on. Strange thing was, there were all these crazy stories I read about complete chaos in the U.S. TONS of people getting arrested for simply saying things bad about President Bush... riots all over the place, and every news article I read about the elections had these stunningly glowing reviews about Kerry and his wife and why most people wanted him to be elected. I remember thinking "Wow Kerry must really be the real candidate of choice if they're having this hard a time staying objective about it." It wasn't even so much 'bad' coverage of Bush, it was all that you heard was about Kerry. And that he was totally awesome.
Came back to the States after the whole election was over and was blown away by the coverage of the U.S. that was displayed in the ol' EU. I was like "Wow, none of the stuff they were saying was happening is going on over here." I thought I was going to come home to some kind of crazy war-torn dictatorship because the Democrat candidate didn't get elected. Needless to say, in my personal experience, the EU media displayed a huuuuuuuuge unapologetic Left Wing bias. Much more so than it is here in the States.
Again, just my personal experience.
Not sure how it is now over there, but if Obama is getting the same kind of coverage Kerry did 4 years ago, its no wonder why our EU brethren are voting heavily for the Big O.
