Field puts the latest results in historical perspective, demonstrating the astonishing reversal in public opinion on this question since 1977:
In 1977 the Field Poll found 28% approving and 59% disapproving of same-sex marriages. In nine periodic surveys taken between that time and 2012, there was a steady increase in support for allowing same-sex couples to marry. The latest survey shows 61% of voters approving and 32% disapproving, a record high level of support.
Examining the results across subgroups of the voter population reveals that there is now majority support for allowing same-sex couples to marry across partisan, ideological, ethnic, age, marital status and the major geographies of the state.
A comparison of the changes in opinions among the sub-groups during just the last three years shows a decline in disapproval among all groups and a correspondingly increase in approval of same-sex marriages.
The only subgroups where majorities remain opposed are registered Republicans and conservatives.
Opinions are about evenly divided among voters age 65 or older and Protestants.I want to emphasize that statement again: "The only [groups] where majorities remain opposed [to marriage equality] are registered Republicans and conservatives."
It's very cool that this poll result comes out in a week in which various parties from the United States Justice Department, major corporations, Republicans, the State of California, pro-gay football players and many others have filed briefs urging Proposition 8 to be struck down by the United States Supreme Court.
