> Less than 4% of Congress members say they're unaffiliated with religion or don't know. PRRI's survey says nearly 27% of the general public is unaffiliated.

THIS is the biggest disparity in the article. Not that X or Y faith or under or over represented, but that almost a full 1/3 of the country is non-religious, yet less than 5% of Congress matches that view point.

We need more openly atheist leaders.
