Bush vs. Kerry

Can anybody please explain to me how big the collective stupidity of a country can get?
I mean sorry, but this 'discussion' between Kerry and Bush was about as equal as a race between a Fiat Panda and Schumacher’s racing-Ferrari. Kerry actually showed that he is able to asses a situation, think it through and come to a conclusion.
Bush on the other hand only proofed that he can't remember more than five sentences.
This doesn't mean that Kerry didn't actually end up with the same slogans all the time as well - the ones, he wanted to hammer into the electorate. But he actually managed to build some sentences around that slogans, that at least gave the impression that he actually tried to answer the question.
Bush on the other hand, if he didn't constantly repeat himself, only looked into the camera, trying to remember what his ghost-writer had told him before. He didn't even pretend, to understand what he was saying. The only message you could get out of him was that he had absolutely no clue whatsoever, about what is going on in the world.
Now I don't say I agreed with everything that Kerry said and to be honest I don't expect a lot out of him winning, but what really is completely beyond my imagination, is who and why anyone could vote for Bush.
I mean, I don't vote for the biggest idiot I can find, do I? After all the function of an election is to vote for someone who will rule over the voter afterwards. And I don't know, maybe I'm just a weird intellectual, but I'd actually want someone who is up for the job.
Bush, if he hadn't all his advisors, wouldn't even find Iraq on a map, let alone understand things like the global economy, globalisation or only the idea of multilateralism. How on earth can you vote for him?????
And why is he still going to win that election? Sorry, but the only conclusion I can find is that the Americans are actually at least as stupid as Bush (then at least they voted for someone equal) . But at the same time, this country is the most powerful in the world, how can it have the collective intelligence of a nut? They have a couple of the best universities, but behave like they never really learned how to read.
God - I know I'm agnostic and don't really believe in you - but if you are somewhere out there, please let Kerry win!
