NYC Mayor-hopeful Bill de Blasio and his wife are both "staunch supporters of gay marriage" but the New York Daily News mentions that before getting married and having two children with his wife, she identified as a lesbian:
De Blasio’s wife, Chirlane McCray, penned a seven-page article for Essence magazine in 1979 titled “I Am a Lesbian” that detailed her emotional path to coming out as a gay woman.
... After the article surfaced Thursday on the Politicker website, de Blasio’s campaign released a statement from McCray.
“In the 1970s, I identified as a lesbian, and wrote about it,” she said. “In 1991, I met the love of my life, married him, and together we’ve raised two amazing kids. I’m reminded every day how lucky I am to have met my soulmate.”
... Essence described McCray at the time as a 24-year-old “free-lance writer.” She wrote that she was “fortunate because I discovered my preference for women early, before getting locked into a traditional marriage and having children.”
