After decades of rising support, same-sex marriage acceptance may be stalling, Gallup poll shows

Nationwide support for same-sex marriage has leveled off and slipped to about 65% (from roughly 71%), ending decades of steady gains.
The change is driven mainly by Republicans—only about 37% now back legal same-sex marriage—widening a clear partisan split while Democrats and independents remain steady.
The political fight continues: some states are pushing bans or protections, transgender policies remain a flashpoint, and the 2015 Supreme Court ruling still faces challenges.
