It’s spreading. In Nevada, a state senator has just introduced a resolution to repeal that state’s ban on gay marriage, LGBTQ Nation reports:
SJR13 was introduced Monday by Democratic Sen. Tick Segerblom of Las Vegas. Same-sex marriage in Nevada was banned in 2002 when voters passed Question 2, the “Protection of Marriage Act,” with 66.9 percent of voters in favor. Now, more than ten years later, polls show sentiment in Nevada for same sex marriage has changed, with many voters supporting it. A February 2013 poll by the Retail Association of Nevada poll found that 54 percent of voters support marriage equality for gay couples.
It’s still a long road – they’d have to approve it this year, again in 2015, and then put it before the voters in 2016.
