The Obergefell v. Hodges ruling held that same-sex marriage is a constitutional right, legalizing it nationwide over a decade ago.

On June 26, 2015, the U.S. Supreme Court ruled 5-4 that states are constitutionally compelled to issue marriage licenses to same-sex couples, legalizing gay marriage nationwide.

Recent polling from Gallup shows that Americans’ support for same-sex marriage is higher than it was in 2015. Gallup’s latest data, however, finds a 47-percentage-point gap on the issue between Republicans and Democrats, the largest since it first began tracking this measure 29 years ago.
