McCain, whose spouse Air Force Reserve Capt. Renee Swift McCain is a black woman, responded to internet racists who felt the ad promoted "miscegenation" by posting photos of his very happy-looking marriage to Twitter.

McCain also mocked racists who insulted him for daring to post a photo of himself and his wife.

Swift McCain also posted her own image of her and her husband, saying they had "bought something" at the retail chain to support Old Navy's embrace of multiracial families.

Gallup polling shows a huge supermajority of Americans, 87%, support interracial marriage, while Pew studies have shown almost all young people see absolutely nothing wrong with it. So the McCains are in solid company, and the haters are just that.
