For example, to become the president of the USA, then you'd best be a believer, or it's not going to happen.
"To become the president of the USA, then you'd best be white, or it's not going to happen." People always think this until it's tested, and then they realise that people don't care as much as they thought they did. The type of people who care about this sort of thing aren't generally swing voters. Australia also has a strong right-wing religious element, and yet they had an atheist woman as their PM not too long ago.
