I saw this article by Mark Mellman in The Hill got very excited. It references how Obama can win a greater percentage of the atheist vote:
Atheists are alienated. Four years ago, they saw an erudite former law professor from an elite university and assumed he must be one of them. Moreover, he was running in the wake of a Republican who constantly injected his religious beliefs into the public dialogue. For obvious reasons, Romney is downplaying his religiosity, while the president’s allies defend him against charges of being a Muslim by celebrating his Christianity. Moreover, the president himself has been seen attending religious functions regularly.
A strategy to win back atheists requires changes in both rhetoric and policy. The president should stop ending his speeches by imploring a nonexistent God to bless America (and his audience). Consider an Oval Office address summoning Americans to overcome their irrational exuberance for the divine. Urge an end to tax deductions for contributions to religious institutions. Although Christmas comes but once a year, and well after the election, it’s never too early to join the war on that holiday.
Then I kept reading the article… DAMMIT! It sounded like such a good idea, too…
For what it’s worth, Obama doesn’t need to do anything to win the atheist vote. We have nowhere else to go. We can choose to not vote, or throw it away on a third party candidate, but it’s not like a significant number of atheists (at least the ones who take social issues and church/state separation seriously) are defecting to the Republican Party.
