The AP reports:
The Field Poll found 78 percent support among people 39 and younger and a solid majority of middle-aged residents now back gay marriage — 56 percent. Even among senior citizens there is 48 percent support, compared with 42 percent against.
The overall results represent a reversal in views about the issue in the 36 years the Field Poll has been taking surveys on gay marriage. In 1977, when the first survey was conducted, only 28 percent approved of gay marriage, while 59 percent were opposed.
According to the poll, 90% of self-identified liberals supported gay marriage compared to 25% of conservatives; 53% or Republicans opposed gay marriage, compared to 39% who approved.
The poll was conducted among 834 registered voters in California just days before the Supreme Court takes up the constitutionality of Proposition 8, which banned gay marriage in the state.
