Washington - This morning Gallup released a groundbreaking poll showing a majority of the American people (53%) support the marriage of committed gay and lesbian couples. This is one of several major polls to confirm the sea change in public opinion on the issue of marriage equality.

"This year marks a significant uptick in support for legalizing same-sex marriage, exceeding the symbolic 50% mark for the first time in Gallup's history," noted the polling organization.

The poll found Democratic and Independent support for marriage equality increased by more than 10 points over the past year. 69% of Democrats, 59% of Independents, and 28% of Republicans support marriage equality.

"The trend toward marriage equality is undeniable -- and irreversible," said HRC President Joe Solmonese. "Marriage for committed, loving couples continues to be an important value of the American people."

Previous polls by CNN, Associated Press, and Washington Post have registered majority support for marriage equality.

"At the moment," writes Gallup, "those advocating changes in constitutions and laws to allow same-sex marriage in additional states can take heart in the apparent shift in national sentiment in their direction."

The Human Rights Campaign is America's largest civil rights organization working to achieve lesbian, gay, bisexual and transgender equality. By inspiring and engaging all Americans, HRC strives to end discrimination against LGBT citizens and realize a nation that achieves fundamental fairness and equality for all.
