Carl DeMaio, an openly gay congressional candidate, on Thursday released an ad which includes his long-term partner.

DeMaio, a former San Diego councilman who lost a 2012 bid for mayor, is one of three openly gay Republican congressional candidates.

In the 88-second ad, titled A New Generation Republican, a female announcer describes DeMaio as a “problem solver who isn't afraid to be different.”

As the narrator says, “He believes in equality and diversity and is a defender of our personal freedoms,” DeMaio is first seen holding hands with partner Jonathan Hale at the San Diego Gay Pride Parade, then waving a rainbow flag.

DeMaio, who is hoping to unseat Democratic Rep. Scott Peters in the 52nd district, told The Wall Street Journal: “This is who I am. It's something that's important to me. I want to embrace equality, and feel like the party should, too.”

However, DeMaio's mayoral candidacy was marred by criticism that he did not speak out against Proposition 8, California's now-defunct gay marriage ban, and for answering that he's single in a questionnaire for The San Diego Union-Tribune, despite his relationship with Hale.

DeMaio told the Journal that campaign consultants persuaded him against including Hale in his mayoral campaign.
