Chris Barron, the chairman of gay GOP group GOProud, has suggested President Barack Obama is pandering to the gay community.

The president on Saturday addressed 3,000 people in Washington at the 15th annual Human Rights Campaign's (HRC) National Dinner. Obama also spoke to the group in 2009.

In his speech, the president touted his record on gay rights, which includes repeal of “Don't Ask, Don't Tell,” the law that for 18 years banned gay and lesbian troops from serving openly, passage of a gay-inclusive hate crimes law, and repeal of the HIV travel ban.

Obama also reiterated his support for repeal of the Defense of Marriage Act (DOMA), the law that forbids federal agencies from recognizing the legal marriages of gay and lesbian couples, and backed passage of the Employment Non-Discrimination Act (ENDA), which would outlaw workplace discrimination based on sexual orientation and gender identity.

“Every single American – gay, straight, lesbian, bisexual, transgender – every single American deserves to be treated equally in the eyes of the law and in the eyes of our society,” Obama told the crowd. “It's a pretty simple proposition.”

However, the president did not, as activists have urged him to do, endorse full marriage for gay couples. He supports civil unions and says he's “evolving” on marriage.

“Barack Obama to the gays – fuck you, not for marriage, vote for me,” Barron, who married his boyfriend Shawn Gardner in the District of Columbia last year, tweeted to his more than 3,000 followers.

“my candidate – Herman Cain – has the EXACT same position on marriage as Obama,” he added about an hour later in response to a tweet.

According to Marriage Equality USA, Cain does not support any form of legal recognition for gay couples.
