New Study - Gay Rights in the States: Public Opinion and Policy Responsiveness
The result are not far from what one could expect:
"Seven states cross the 50% mark overall as of our current estimates, but the generation gap is huge. If policy were set by state-by-state majorities of those 65 or older, none would allow same-sex marriage. If policy were set by those under 30, only 12 states would not allow-same-sex marriage."
