Writing in the Columbus, Ohio, Dispatch , Rob Portman proves his credentials as a Good Republican.

When he found that his son is gay, he questioned his earlier opposition to gay marriage: “I wrestled with how to reconcile my Christian faith with my desire for Will to have the same opportunities to pursue happiness and fulfillment as his brother and sister. Ultimately, it came down to the Bible’s overarching themes of love and compassion and my belief that we are all children of God.”

And like David Cameron, he argues that he supposed gay marriage out of conservative principles rather than in defiance of them: “We conservatives believe in personal liberty and minimal government interference in people’s lives. We also consider the family unit to be the fundamental building block of society. We should encourage people to make long-term commitments to each other and build families, so as to foster strong, stable communities and promote personal responsibility.”
