The largest slice of President Barack Obama’s religious coalition -- at 23 percent -- is not very religious. They’re the “nones,” also known as unaffiliated voters, according to a new American Values Survey by the Public Religion Research Institute.
President Obama says it’s not his job to defend his Christian faith against doubters who suspect he’s Muslim. His GOP challenger, Mitt Romney, says religion is “integral” to his life, even as often he avoids mentioning his Mormon faith by name.
