I don't know why my post was modded down. Apparently atheists are highly discriminated against, even within "enlightened" groups.
To my astonishment a very recent Gallup poll indicated that, of many groupings, atheists were _least_ likely to be elected President of the US (e.g., _well_ behind Mormons, homosexuals, 72-year-olds, etc.):
We've never had an atheist president, but we've had deists (whom most evangelicals would discount as Christians) including Washington, Jefferson, and Lincoln. We've also had Unitarian presidents, such as John Adams.
