A new Public Policy Polling survey in Maryland finds a significant increase in support for same-sex marriage among African American voters following President Obama’s historic announcement two weeks ago. The referendum to keep the state’s new law legalizing same-sex marriage now appears likely to pass by a healthy margin. Here are some key findings:
-57% of Maryland voters say they’re likely to vote for the new marriage law this fall, compared to only 37% who are opposed. That 20 point margin of passage represents a 12 point shift from an identical PPP survey in early March, which found it ahead by a closer 52/44 margin.
-The movement over the last two months can be explained almost entirely by a major shift in opinion about same-sex marriage among black voters. Previously 56% said they would vote against the new law with only 39% planning to uphold it. Those numbers have now almost completely flipped, with 55% of African Americans planning to vote for the law and only 36% now opposed.
