(CNN) - Bias against a Mormon presidential candidate hasn’t budged in 45 years, with 18% of Americans saying they would not vote for a well-qualified candidate who happened to be Mormon, according to a Gallup Poll released Thursday.
The survey points up potential challenges for presumptive Republican presidential nominee Mitt Romney, who is vying to be the first Mormon in the White House.
Gallup first asked Americans about support for a Mormon presidential candidate in 1967 when Romney’s father, George Romney, was running for president. That year, 17% of Americans said they would not vote for a well-qualified Mormon for president.
