Any Non-Christians running?

This seems to be a cycle without any Jewish candidates with a plausible shot at the nomination for either party.

That could change in later cycles. The Democrats have a decent bench of officeholders.

Atheists have a tougher challenge, but there is one guy with the resources to pull off a presidential challenge in an environment where the public prefers an outsider. He happens to be one of the most popular people in the country: Bill Gates.

Obviously, there are probably some closet atheists with a chance at getting elected to significant political office.
