Atheists are not big enough to have their own category in this graph,

Wouldn't they be in the 'Seculars' category?

I’m not sure that they meant that all the secular are atheists, but of course all atheists would be in that grouping.

It is clear that atheists, or secular are overwhelmingly liberal, unlike the committed Christians that are overwhelmingly conservative.
