Who are the most Republican voters in America? And the most Democratic?

The Pew Research Center is out with a massive study (more than 25,000 interviews!) breaking down pretty much any sub-demographic you could think of -- allowing us to dig much deeper than just any old poll would allow.

According to the study, the most Republican-leaning group in America is white Mormons, 76 percent of whom favor the GOP and 16 percent of whom favor Democrats -- a 60-point margin.

(Note: These numbers include self-described independents who lean toward either party. These are also broken down only into groups that represent a significant chunk of Americans.)

The next most Republican group is also white and religious -- white evangelical millennials (adults under 34), who split 70/19 for the GOP. Mormon and evangelical sub-groups account for the rest of the top eight, too, until you get to men from the Silent Generation (between ages 69 and 86), who split 60/31 Republican, and a three-way tie to round out the top 10 between white married men, white male parents and whites from the South Central region (Alabama, Arkansas, Kentucky, Louisiana, Mississippi, Oklahoma, Tennessee and Texas).

Here are the top 10 most Republican demographics ("NH" stands for non-Hispanic, "Xer" is Generation X, etc.). There are actually 12 since there is a three-way tie at the bottom:

Demographic Republican/lean Republican Democratic/lean Democratic
White NH Mormon 76 16
White NH Evangelical Protestant Millennial 70 19
White NH Evangelical Protestant Xer 70 20
Mormon 70 22
White Non-Hisp Evangelical Protestant 68 22
White NH Evangelical Protestant 68 22
White NH Evangelical Protestant Boomer 68 23
White NH Evangelical Protestant Silent 67 25
White NH Silent men 60 31
White NH Married men 58 32
White NH Parent men 57 31
   White NH South Central (AL AR KY LA MS OK TN TX) 58 32

 

Since white Americans dominate this list, here are the top 10 demographics that don't isolate them:

Demographic Republican/lean Republican Democratic/lean Democratic
Mormon 70 22
Silent men 54 37
Married men 51 38
Rural 47 39
Married 48 41
Older Silent (79-86) 48 43
Silent (69-86) 47 43
Younger Silent (69-78) 47 43
$75,000 to $99,999 48 44
College men 47 43

 

And while almost all of the most Republican groups are white, almost all of the most Democratic groups are African Americans, who as a whole tilt 80/11 toward Democrats. In fact, each of the top 56 most Democratic groups broken down by Pew are some sub-group of black Americans.

Here are the top 10 most Democratic groups:

Demographic Republican/lean Republican Democratic/lean Democratic
Black NH Silent women 4 89
   Black NH Post graduate degree 5 87
Black NH No 6 88
Black NH Older Boomer (59-68) 8 89
Black NH Silent (69-86) 7 87
Black NH Gen Xer women 6 84
Black NH Boomer women 8 86
   Black NH Some college 8 85
Black NH $50,000 to $74,999 8 85
Black NH $40,000 to $49,999 8 85

 

The most Democratic groups that aren't black are white atheists (73/16) and all atheists (72/16), followed by Asian American women (73/17).

Here are the top 10 non-black groups:

Demographic Republican/lean Republican Democratic/lean Democratic
   White NH Atheist 16 73
   Atheist 16 72
Asian NH Women 17 73
Asian NH Millennial (ages 18-33 in 2014) 17 70
Asian NH <$30,000 17 69
   Agnostic 23 69
   White NH Agnostic 24 67
Asian NH Some college or less 23 66
Asian, non-Hispanic (English-speaking) 23 65
Hispanic Older Boomer (59-68) 23 65

 

The interesting ones here are Asian Americans, who as a whole favor Democrats 65/23. That's notable because Republicans won the Asian American vote in the 1992 and 1996 presidential elections. These voters have swung very blue in recent years, though, going 67 percent for President Obama in 2008 and 73 percent for him in 2012 -- one of the rare groups that moved more toward the Democrats in the latter election.

One of the other big takeaways here: The most Democratic groups are all much more homogeneous than the most Republican groups. Even when you get beyond whites and blacks, there are 10 groups who are at least 65 percent Democratic-leaning, but only one on the GOP side (Mormons).

And if that's not enough, here are all the cross-tabs you could possibly want.
