The differences in Obama's approval ratings across the religious groups included in this analysis have held fairly constant across time, even as Obama's overall rating has fallen by 15 percentage points between the first half of 2009 and the first seven months of this year. American Muslims -- in the news recently with the controversy over proposed plans to build an Islamic center and mosque near ground zero in New York City -- have given Obama his highest ratings in all three time periods: 86% in the first half of 2009, 83% in the second half of 2009, and 78% so far this year. Mormons have given Obama his lowest ratings across time, dropping from 43% in the first half of 2009 to 24% this year.
In addition to Muslims, Obama receives above-average ratings among Jews, those who identify with other non-Christian religious groups, and those with no formal religious identity. Obama gets lower-than-average ratings among Protestants. Catholics have given Obama slightly higher-than-average ratings last year and so far this year.
