There's an article at Slate today on the likelihood of other minorities making it to the highest office in the land. Here's the money quote:
When the lion lies down with the lamb, when the president is a Republican Muslim and the Democratic speaker of the House is a vegan Mormon lesbian, when the secretary of defense is a Jain pacifist from the Green Party, they will all agree on one thing: atheists need not apply. A 2007 Gallup poll found that 53 percent of Americans would not vote for an atheist for president. (By contrast, only 43 percent wouldn't vote for a homosexual, and only 24 percent wouldn't vote for a Mormon.) As Ronald Lindsay, executive director of the Council for Secular Humanism, told me in an e-mail: "Atheism spells political death in this country."
Or am I being too optimistic?
