For the past 15 years or so, Gallup has charted how Americans describe themselves when it comes to social and economic issues.
For the first time ever, equal percentages of us define ourselves as liberal and conservative on social issues:
Even among Republicans, social liberalism is ascendant, with self-described conservatives dipping from a low of 67 percent in 2009 to just 53 percent now. The key issues driving the growth of social liberal views and the decline of social conservative views, says Gallup, are gay marriage and pot legalization. Support for both of those things has skyrocketed in the 21st century, with a velocity that is nothing short of stunning.
