Gay marriage supporters in Washington state on Friday released their first Referendum 74 ad with Republican Senator Cheryl Pflug as its star.

Pflug was one of two senators who spoke out in support of marriage equality as the state Senate debated – and ultimately approved – a gay marriage bill in January. The other Republican was Senator Steve Litzow.

Referendum 74 will ask voters in November to either uphold or overturn the marriage law.

“I know a number of gay and lesbian couples that have been together for 40 years,” Pflug says in the 30-second spot. “I saw in these couples love, commitment, a sharing of a life together – everything that makes for a good marriage.”

“As a Republican, I believe in freedom. And that includes the freedom to marry the person you love,” she adds. (The video is embedded in the right panel of this page. Visit our video library for more videos.)

The ad debuted during the Olympics opening ceremony and will run several times a day in three Washington media markets over the course of the next two weeks.

The television advertisement was paid for by Seattle-based Pride Foundation, whose executive director, Kris Hermanns, would only tell the AP that the ad buy “will be in the six figures.”
