I found this piece on a blog in KY.  A group called Faith In America is highlighting high profile interracial couples as examples of why the freedom to marry should be extended to gay couples.  In short, the group is pointing out that these couples, among them conservative Republicans who oppose marriage equality, would once have been forbidden to get married based on their races.  Senate Minority leader Mitch McConnell and his wife Secretary of Labor Elaine Chao are among the couples listed.  

Faith In America list its missions as the following:

"The mission of Faith In America, Inc. is the emancipation of lesbian, gay, bisexual and transgender people from bigotry disguised as religious truth. The world's great religious traditions practiced within the United States of America emphasize the love of neighbor as well as the love of God. Compassion, justice, freedom, and respect for the dignity of all people are their most authentic and noble expressions."
