Fresh from a controversy over his views on evolution, Wisconsin Republican Gov. Scott Walker is now involved in a controversy over his views, or lack of them, on President Obama’s religion. On Saturday, two Washington Post reporters asked Walker, in the nation’s capital for a governor’s meeting, whether Obama is a Christian. Walker said he didn’t know.

Informed by the reporters that Obama is in fact a Christian, Walker replied, “I’ve actually never talked about it or I haven’t read about that,” protesting that the president’s religion is not a topic of great interest to voters. “I would defy you to come to Wisconsin. You could ask 100 people, and not one of them would say that this is a significant issue,” Walker told the Post.
