Over the past four years, support for same sex marriage increased by 8, from 47% to 55%. At the same
time, opposition dropped by 12, from 49% to 37%. This resulted in an increase in net support of +20.
Gains in support are greatest among Republicans (+12), middle aged voters (+13 for 30 to 44 year olds and +17 for 45 to 64 year olds), African Americans (+14), and those who know a gay or lesbian personally (+10).
Those who know gays or lesbians are significantly more likely to support same sex marriage. Those who know a gay or lesbian person are 62% supportive and only 32% opposed. Those that do not know anyone who is gay or lesbian are 36% supportive and 53% opposed.
