NEW YORK President Barack Obama retains the support of 78 percent of Muslims, compared with 61 percent of Jews, 43 percent of Protestants, 50 percent of Catholics and 24 percent of Mormons, the Gallup poll has found. Obamas support dropped among voters of all religions since he assumed the presidency 17 months ago - but less so among Muslims, it said. His backing from Muslims had been 86 percent a year ago. By comparison, Obamas support plummeted 15 points among Protestants, 17 among Catholics, 16 among Jews, 21 among Mormons and more than 10 among people of other religions or no religion. The latest survey, in which Muslim Americans gave President Obama an approval rating of 78 percent, was completed on July 31, before the President gave a speech at the White House on Aug. 13 defending the right of Muslims to build a mosque in lower Manhattan. Also, a new poll released Thursday conducted by the Pew Forum on Religion and Public Life found that nearly one in five Americans falsely believe Obama is a Muslim, up from around one in 10 Americans who said last year they believed he was Muslim. While most of those who think Obama is Muslim are Republicans, the number of independents who believe he is Muslim has expanded significantly, from 10pc last year to 18pc now, according to the Pew survey. The White House stated unequivocally on Thursday that Obama is a Christian.
