Samuel G. Freedman in the New York Times:
One problem with turning out the atheist vote is finding it. Atheists do not reside visibly in certain neighborhoods like blacks or Hispanics or gay men and lesbians. They do not turn up on the databases of professional associations like doctors or lawyers. And as nonbelievers, they axiomatically do not come together for worship.
