This frame grab taken from YouTube on Tuesday, Sept. 17, 2012 with permission of Minnesotans United for All Families shows John, left, and Kim Canny, Catholic Republicans from Savage, Minn., in a commercial in which they say they oppose a proposed constitutional amendment this November that would ban gay marriage. Like almost all the subjects of ads in favor of gay marriage, the Cannys are straight. Some gay activists question an ad strategy that rarely puts actual gay people on camera, saying it contradicts their philosophy of openness and hasn’t worked. But political strategists say they need to win over moderates and can’t do it by making them uncomfortable. (AP Photo/Minnesotans United for All Families)
