Utahns now evenly split on gay marriage
For support and legality of same-sex marriage.
White -- same-sex marriage legal or has at the least been enacted. No further distinction.
Green -- same-sex marriage not legal, but more popular than unpopular or plurality support for legalization of SSM
65% or higher -- deep green (90% saturation)
60.0 - 64.9% -- dark green (70% saturation)
55.0 - 59.9% -- medium green (50% saturation)
50.0 - 54.6% -- light green (30% saturation)
below 50% but positive -- aqua (20% saturation)
tie -- yellow
above 45.0% but negative -- hot pink (30% saturation)
40.0 - 44.9% -- medium red (50% saturation)
35.0 - 39.9% -- red (60% saturation)
30.0 - 34.9% -- maroon (70% saturation)
under 30% -- deep red (90% saturation)
As stated in that poll, some of the support might just be from people who oppose SSM, but don't think that the court's decision should be challenged (as the question is phrased "should SSM get marriage licenses?", not "do you support SSM?"
Still, roughly two years after the last poll, this seems promising. At this point, I honestly think that the majority of Utahns under 30 support SSM (Much like Georgia).
