A majority of Americans oppose the Defense of Marriage Act (DOMA), the 1996 law which prevents the federal government from recognizing the legal marriages of gay and lesbian couples.

According to a national survey released Tuesday and commissioned by the Center for American Progress (CAP) and Gay & Lesbian Advocates and Defenders (GLAD), 59 percent of registered voters oppose DOMA.

Opposition is strongest among African-Americans (61%), followed by Hispanics (61) and whites (57%).

When asked if β€œit is discriminatory for the federal government to deny marriage protections and benefits to legally married same-sex couples,” 62 percent of respondents answered yes.

A majority (52%) of respondents also said they support marriage rights for gay couples.

President Barack Obama supports a legislative effort to repeal the law. However, that approach is not expected to make any headway under the current Republican-controlled House.

One of two Supreme Court cases related to marriage seeks to strike down portions of DOMA. The court is expected to hear United States v. Windsor next month and hand down a ruling in June.
