Public opinion on same-sex marriage has shifted remarkably quickly — twice as many Americans supported it in 2014 as in 1996. And a new Gallup poll shows it's gaining even more momentum.
Support for same-sex marriage rose 5 percentage points in just one year, from 55 percent in 2014 to 60 percent now.
Much of the upswing is among self-described independents or Republicans. Democratic support for same-sex marriage only went up 2 percentage points from 2014 to 2015, but independent support jumped 6 percentage points — and Republican support jumped 7 percentage points.
