A radio spot launched Thursday by Marylanders for Marriage Equality features President Barack Obama's gay marriage endorsement.

In the ad, two women discuss how they're going to vote for Question 6, the November 6 ballot question which asks voters to uphold – or reject – a gay marriage law approved by lawmakers.

One woman tells the other that she's unsure about how to vote on the measure.

“I didn't know either, but then I heard President Obama supported marriage for gay couples.”

“Really?” the woman asks.

“You haven't heard him? I've got the clip here on my phone … It's that important … Listen up.”

“Same-sex couples should be able to get married. I had hesitated on gay marriage because I thought civil unions would be sufficient,” Obama is heard saying. “You know, Malia and Sasha, they've got friends whose parents are same-sex couples, it wouldn't dawn on them that their friends' parents would be treated differently. That's the kind of thing that prompts a change of perspective. When we think about our faith, it's also the golden rule…”

“Obama makes it so simple,” the previously undecided woman says, “it's about fairness – treating everyone equal under the law.” (The audio is embedded on this page. Visit our video library for more videos.)

The Obama spot was funded with $100,000 from Freedom to Marry, the nation's largest marriage equality advocate. The group's contribution will also go to support an ad featuring civil rights hero Julian Bond.
