The never-clearing fog around Obama's religion

In February, Scott Walker, in response to a reporter’s question, said he did not know if President Obama is a Christian. Controversy ensued, with pundits pressuring Walker to affirm that the president is in fact a Christian. Walker argued that voters looking to the 2016 presidential race don’t care. The controversy eventually faded.

Now, Donald Trump is in the middle of a new edition of the controversy, having failed to correct an Obama-is-a-Muslim statement made by an unidentified participant in a New Hampshire town hall. Again, controversy has erupted, with pundits pressuring Trump to affirm that Obama is in fact a Christian.
