Interesting poll

Gallup just did a poll asking people whether they would vote for a Catholic, a Mormon, a Jew, a Black person, a Hispanic, a woman, etc. Here's the data:

If Your Party Nominated A Generally Would You Be Comfortable
In Voting Well-Qualified Candidate For WH '08 For A WH
'08er Who Was ___,  Would You Vote For That Person?   
                                     
                         Yes  No                 
Catholic                  95%  4%                          
Black                     94   5  
Jewish                    92   7   
A woman                   88  11        
Hispanic                  87  12   
Mormon                    72  24 
Married for third time    67  30  
72 years old              57  42
A homosexual              55  43   
An atheist                45  53 

Apparently there are 159,630,450 Americans who would never vote for me for President based purely on my lack of religious faith. To me it's strange that the most people would never consider voting for an atheist, yet atheists aren't historically as persecuted as gays, Jews, or a lot of the groups in that list; gays, Jews, blacks, etc. have been murdered for being gay, Jewish or black, but I'm unaware of any of that happening to atheists.
I am reminded that, in terms of national politics, we have Catholic, Jewish, black, Hispanic, female, Mormon, divorced, gay and old Congressional Representatives, but no atheists yet. I'm disappointed they didn't ask about Muslims. That would be a fascinating data point to track over time.
