A Gallup survey released Wednesday reported its highest support yet for allowing gay and lesbian couples to marry.

When pollsters asked 1,028 adults, ā€œDo you think marriages between same-sex couples should or should not be recognized by the law as valid, with the same rights as traditional marriages?ā€ 55 percent answered that such unions should be valid. Forty-two percent said they should not.

Gallup first recorded majority (53%) support for marriage equality in 2011.

The polling firm noted that while only 30 percent of Republicans support same-sex marriage, they have nearly doubled their support for it since 1996, the first year Gallup asked the question.

However, a Washington Post-ABC News survey conducted in March found even higher support, with 59 percent of participants saying they support allowing gay couples to marry.
