Some highlights:
One in five conservatives voted no while one in five liberals voted yes.
Seventy percent of those who attend religious services weekly voted for the ban.
While more than two-thirds of those 65 or older supported Proposition 8, the majority under 65 opposed it.
Despite the ban’s passage, support for marriage equality increased 9 percent since voters approved a similar ban in 2000. Support increased among every age group under 65 and demographic exception Republicans.
About 60 percent of those who voted for Proposition 8 reported not having any gay or lesbian friends or family.
Party affiliation and ideology had a considerable impact, affecting 30 percent of voters, trumping gender (5 percent), race (6 percent), age (9 percent) and religiosity (12 percent).
The whole article on the polling is worth reading. Interestingly, this poll also illustrates that Prop 8 support among African Americans wasn’t as overwhelming as origninally thought. According to a press release put out by several gay rights groups:
Moreover, the study found that the level of support for Proposition 8 among African Americans was nowhere close to the NEP exit poll 70 percent figure. The study looked at pre- and post-election polls and conducted a sophisticated analysis of precinct-level voting data from five California counties with the highest African-American populations (Alameda (Oakland), Los Angeles, Sacramento, San Diego and San Francisco).[1] Based on this, it concludes that the level of African-American support for Proposition 8 was in the range of 57-59 percent. Its precinct-level analysis also found that many precincts with few black voters supported Proposition 8 at levels just as high or higher than those with many black voters.
As discussed earlier, the 57-59 percent figure - while higher than white and Asian-American voters - is largely explained by the higher rates of African-American church attendance: 57 percent of African Americans attend church at least once a week, compared to 42 percent of whites and 40 percent of Asian Americans.
