"Check it out, almost half of Americans didn't vote for Bush."

Far more than that. Almost half of them didn't vote for anyone. You get their point too.

When non-Americans are rude about Americans it often means they are looking at what they expect they might be like a few years down the one, and they don't like the thought. It's a kind of "God Forbid!"

But generally the kind of things people go on about when in that mood are the same things a whole lot of Americans don't much like too.
