At the other end of the political spectrum, nearly eight-in-ten white evangelical Protestants voted for Romney (79%), compared with 20% who backed Obama. Romney received as much support from evangelical voters as George W. Bush did in 2004 (79%) and more support from evangelicals than McCain did in 2008 (73%). Mormon voters were also firmly in Romney’s corner; nearly eight-in-ten Mormons (78%) voted for Romney, while 21% voted for Obama. Romney received about the same amount of support from Mormons that Bush received in 2004. (Exit poll data on Mormons was unavailable for 2000 and 2008.)
Compared with religiously unaffiliated and Jewish voters on the left and white evangelicals and Mormons on the right, Catholics and white mainline Protestants were more evenly divided. Among white mainline Protestants in the exit poll, 54% voted for Romney, while 44% supported Obama. This is virtually identical to the 2008 election, when 55% of white mainline Protestants voted for McCain and 44% backed Obama.
White Catholics, by contrast, swung strongly in the Republican direction relative to 2008. Nearly six-in-ten white Catholics (59%) voted for Romney, up from 52% who voted for McCain in 2008. Three-quarters of Hispanic Catholics voted for Obama, and Catholics as a whole were evenly divided in 2012 (50% voted for Obama, while 48% backed Romney) - http://www.pewforum.org/Politics-and-Elections/How-the-Faithful-Voted-2012-Preliminary-Exit-Poll-Analysis.aspx
The question is — why did 20% of white evangelicals vote for Obama? There is no historical reasoning for the vote (which some Catholic idiots who voted for Obama can use as an excuse) — why would evangelicals vote Democrat?
we can eliminate the Latino evangelicals from that 20% (as even among evangelicals Latinos, more voted for Obama than for Romney), but still a significant percentage of white evangelicals voted for Obama. What could be the reason?
