(AP Photo/Matt Young, File) Sisters, there were never such bickering sisters: Dick Cheney's daughters are going mano a mano over the issue of gay marriage, with Mary Cheney—who is gay and married longtime partner Heather Poe last year—now responding to sister Liz's stance against it. “For the record, I love my sister, but she is dead wrong on the issue of marriage," she posted on Facebook. "That means that all families—regardless of how they look or how they are made—all families are entitled to the same rights, privileges, and protections as every other." Mary Cheney and Poe have two children. "Freedom means freedom for everyone," she wrote, in what the New York Times notes is similar verbiage to dear old dad's support of gay marriage.
