The NBC News national exit poll found that midterm voters are evenly divided — 48% supporting and 48% opposed — on the legality of same-sex marriage, similar to the views of voters in the 2012 presidential election.

Support for gay marriage had been building over the past few election cycles. Four years ago, 41% of voters nationwide said same-sex marriage should be legal in their home state. In 2012, 49% of voters supported it.
Proponents of gay marriage have seen huge gains since the Supreme Court struck down the Defense of Marriage Act in June 2013. In 32 states and Washington, D.C., same-sex couples can now marry legally. Kansas would become the 33rd state to recognize gay marriage if the state’s attorney general does not appeal a court ruling that struck down a gay marriage ban there.
Support for the issue has shifted most dramatically among younger voters. In 2010, a bare majority — 52% — of voters under the age of 30 said same-sex marriage should be legal in their state. Now, that number stands at 64%.
