Just a few years ago, should you ask the average person what each major political party stood for, you could have expected a fairly standard answer. The GOP: tax cuts, deregulation, and a strong national defense. The Democratic Party: universal healthcare, marriage equality, and climate action. In today’s populist moment, the answers may not seem so clear, but the truth is that each party’s priorities have been shifting for some time now — some subtly, while others quite obviously.

It was not too long ago that both the Republican Party and the Democratic Party stood in opposition to a concept now widely accepted: marriage equality. Today, a record 70% of people find themselves in support of same-sex marriage, 10% higher than when the Supreme Court ruled that states must recognize such unions in 2015.
