In the news

It seems I'm wrong. Thought about this a bit more. It looks like Americans would vote for a non-believer. However, my point about thin margins above stands. Presumably the majority of this 54% are Democrats. With margins of a few percentage points, you only need a small number of the 54% to be Democrats for a Republican (and presumably non-atheist) win.

For the second time in less than a year, the Gallup poll reports that a majority of Americans would vote for an atheist for president.

The latest survey, from June, found that 54 percent of those asked said they would vote a "well- qualified" atheist into the Oval Office— the highest percentage since Gallup began asking the question in 1958, when only 18 percent said they would back a nonbeliever.
In any case, the point remains. I think people are overstating the religiosity of America as a whole. It has crazies just like the UK, Ireland, Poland, Italy, Norway, blah, blah, blah. Maybe more of them, but it does't mean everyone in the US is one of them.
