What does it matter in view of the presidency? The president doesn’t set theological standards.

[Verginius Rufus]

It reminds me of the passage in the New Testament when the Pharisees and Herodians ask Jesus if it is permissible to pay the tribute money to Caesar. They were trying to trap him into saying something that would get him in trouble with the Jewish masses or in trouble with the authorities.

Likewise the question to Walker was meant to trick him into saying something that would alienate his followers or else make it easy for the media to portray him as ignorant and anti-science.

The Constitution does say that no religious test shall be required for federal offices but that's another matter.
