Could an atheist win the White House? It's not as crazy as you might think.

These are pretty good times for non-believers.

Our ranks are growing rapidly, with nearly a quarter of Americans now
 claiming no religious identification. Even if most of those don't
 emphatically declare themselves atheist, but say their religion is "nothing
 in particular," there are surely plenty of people who call themselves
 Catholics or Jews or something else but whose belief in an all-knowing,
 all-seeing god is tenuous at best. The number will keep growing, because
 religiosity and age are strongly correlated today, with older people being
 the most religious while a full third of millennials claim no religion.
 It's no longer considered scandalous in many, if not most, places to say
 that you aren't a believer. And the War on Christmas is going pretty well,
 too (kidding).
