In the more than four years since that column was published, it's likely at least some confusion about Obama's religion has persisted. For one thing, few people see Obama openly practicing any religious faith. After the president did not attend church on Christmas 2013, the New York Times, citing unofficial White House historian Mark Knoller, noted that Obama had attended church 18 times in nearly five years in the White House, while George W. Bush attended 120 times in eight years. Yes, there are a variety of reasons some presidents don't go to church very often, but in Obama's case, absence does nothing to change existing public perceptions of him.
And there are other factors. For example, it would not be a stretch to guess that those Americans who told Gallup and Pew that they did not know the president's faith would remain unsure after hearing reports that at the recent National Prayer Breakfast, Obama explained Islamic State violence by urging listeners to "remember that during the Crusades and the Inquisition, people committed terrible deeds in the name of Christ." Again, many people don't pay close attention to the news, and snippets of reports on Obama's faith, like his remarks at the Prayer Breakfast, could yield a confused picture.
Some would argue that, while yes, many in the public don't know the president's religion, certainly Scott Walker, the governor of a state, should know. But Walker's answer to the reporters' question just reflects a broader public puzzlement over Barack Obama's faith — a phenomenon that he helped perpetuate and, at this late date in his presidency, seems unlikely to go away.
"Gosh, of course less than half of America thinks Obama is Christian. He's terrible at it." And so the racist, bigoted assholes like York keep concern trolling the President that he's not Christian enough, and absolve the "He's a seekrit Mooslem" nonsense all in the same breath.
And of course, York's bigotry is all Obama's fault. It always is.
