Hysterical claims that Young Republicans are just the same as young Democrats on same-sex marriage have been pointing to recent exit shitpolls. While the GSS was completed before the election, we may get some inkling of how far off such logic is from the true state of affairs. Remember, our quintessential socially liberal young Republican is Meghan McCain, not Newt Romney, or Tag or whatever. Above it is evident that support for same sex marriage is substantially higher among Obama voters across all age groups—though there is more age-variance among Republicans. In fact, Obama voters under 50 are mostly all similar. And, we should remember that our Obama voters include a substantial proportion of African Americans–who tend to be less supportive of Same sex marriage.
Just splitting the sample by under 50 over 50 provides some interesting contrasts. Less than 40% of McCain voters under age 50 supported same sex marriage on the heels of the 2012 election–while 72% of Obama voters under age 50 from 2008 supported same sex marriage in 2012. If we focus on whites, only 38% of white McCain voters under 50 supported same-sex marriage in 2012. However, 82% of 2008 Obama voters supported same sex marriage in 2012—a 44% gap!
