State Democratic parties in Texas, Montana and Pennsylvania are supporting gay marriage in their 2012 platforms.

Pennsylvania Democrats over the weekend endorsed a gay marriage resolution sponsored by Adams County Democratic Chair Roger Lund, who is openly gay. reported that the voice vote was overwhelmingly (85 to 90%) in favor.

The move comes less than 3 weeks after Jo Ann Nardelli, a former Democratic state committeewoman, defected from the party over President Barack Obama's endorsement of such unions.

At their state convention in Houston over the weekend, Texas Democrats also approved a marriage equality plank.

“Texas Democrats join President Barack Obama and Vice President Joe Biden in calling for and affirming equal rights including marriage equality for all Americas,” a portion of the resolution states. “We, along with our President and Vice President, recognize that same sex marriages should be valid and legal in America. … We support the repeal of the Federal Defense of Marriage Act, the Texas Defense of Marriage Act and the Texas Constitutional Marriage Amendment and oppose other attempts to deny the freedom to marry to loving same sex couples.”

According to, Erin Moore, outgoing Vice Chair of Texas Stonewall Democratic Caucus, proved instrumental in getting the resolution to the convention.

Montana Democrats unanimously adopted a resolution which calls for repeal of the state's constitutional ban on gay marriage, the Independent Record reported.

Members moved to remove existing language supporting civil unions for gay couples and replaced it with marriage. “We support repealing Section 7, Article 13 of the Montana Constitution. All adults should have the right to legally marry another adult of their choice, regardless of sex or gender. We believe same-sex spouses should have the same legal benefits, protections and responsibilities granted to all those who marry,” the resolution states.
