Nearly 2 weeks after President Barack Obama came out in support of gay marriage, opposition has hit a record low, a new poll has found.

According to the Washington Post/ABC News poll, support among Americans for the institution has hit a record high of 53 percent. In 2006, only 36 percent thought it should be legal. Thirty-nine percent remain opposed, a record low.

Pollsters also reported a nearly 20 percent increase in support among African Americans (from 41% to 59%) but warned against any conclusions considering the poll's relatively small sample of black voters.

Obama, who previously endorsed civil unions for gay and lesbian couples, announced his shift to marriage in an interview with ABC's Robin Roberts. He credited his gay friends and daughters Sasha and Malia with influencing his decision.

“By speaking in very personal terms about his own journey, the president has helped to build a larger and stronger majority in support of full equality for committed gay and lesbian couples,” the Human Rights Campaign's (HRC) Fred Sainz told The Washington Post.

For the first time, “strong” support (39%) for gay marriage outstripped “strong” opposition (32%).
