A new poll finds that 29 percent of Americans think President Barack Obama is a Muslim.

The CNN/ORC survey also shows that 1 in 5 Americans — 20 percent — believe the American president was born outside of the United States. The U.S. Constitution requires that a president be a natural born citizen.

OBAMA’S RELIGION (according to CNN/ORC poll respondents)

Protestant/Christian…39%
Muslim…29%
No opinion…14%
Not religious…11%
Catholic…4%
Mormon…2%
Jewish…1%
Something else…1%

Obama was born in Hawaii, a U.S. state, and has repeatedly said he identifies as a Christian.

In 2011, in response to a resurgence of the “birther” movement that questioned Obama’s qualification to be president based on their belief he was born outside the U.S., the White House posted a certified copy of his birth certificate, which shows he was born at Kapiolani Hospital in Honolulu, Hawaii, on August 4, 1961.

While more Republicans than Democrats believe Obama was born outside the United States, the vast majority of GOP-leaning voters — 71 percent — do believe he is a natural born citizen.

While about 3 in 10 Americans think Obama is a Muslim, 45 percent do say they believe he is some sort of Christian — either Protestant, Catholic or Mormon. Fourteen percent of respondents have no opinion on the matter while 11 percent, when asked the president’s religion, said he is not religious.

There appears to be an education gap when it comes to people’s opinions. Most people who earned a college degree — 63 percent — agree that Obama is a Protestant while 28 percent of those without a college degree say that he is.

The poll includes 1012 adults who were interviewed by telephone nationwide. Of those interviewed, 27 percent described themselves as Democrats, 24 percent said they were Republicans and 49 percents identified as independents or members of another party.
