This answer reveals he gets the issues more than any other candidate, he even understands taqiyya.

Republican presidential hopeful Ben Carson is standing by his view that a Muslim should not be president of the United States, telling The Hill in an interview on Sunday that whoever takes the White House should be “sworn in on a stack of Bibles, not a Koran.”

Carson ignited a media firestorm in a Sunday morning interview with Chuck Todd on “Meet the Press,” in which he said he “would not advocate that we put a Muslim in charge of this nation.”
“I absolutely would not agree with that,” Carson said.

In an interview with The Hill, Carson opened up about why he believes a Muslim would be unfit to serve as commander in chief.

“I do not believe Sharia is consistent with the Constitution of this country,” Carson said, referencing the Islamic law derived from the Koran and traditions of Islam. “Muslims feel that their religion is very much a part of your public life and what you do as a public official, and that’s inconsistent with our principles and our Constitution.”

Carson said that the only exception he’d make would be if the Muslim running for office “publicly rejected all the tenets of Sharia and lived a life consistent with that.”

“Then I wouldn’t have any problem,” he said.

However, on several occasions Carson mentioned “Taqiyya,” a practice in the Shia Islam denomination in which a Muslim can mislead nonbelievers about the nature of their faith to avoid religious persecution.
