In U.S., Very Religious Americans Still Align More With GOP In May, 2011, Very Religious Were 19 Percentage Points More Likely to Be Republican The detailed breakdown of approximately 30,000 interviews conducted in May 2011 shows that very religious Americans are 19 percentage points more likely to identify as Republicans than are the nonreligious, 48% vs. 29%. Very religious Americans are 10 points more likely to be Republican than Democratic ----48% vs. 38%. Among moderately religious Americans, there is a Democratic advantage of 8 points. Among nonreligious Americans, the Democratic advantage increases to 25 points. Does this mean that Republicans generally have a lower IQ? I mean believing a 2000 year old fairy tale says a lot. Maybe that's why they go to the polls and vote for the rich people when they're average or less.
