But it’s difficult to get people even to consider your reform ideas if they think, with good reason, you don’t like or respect them. Building a winning coalition to tackle the looming fiscal and trust deficits will be impossible if we continue to alienate broad segments of the population. We must be happy warriors who refuse to tolerate those who want Hispanic votes but not Hispanic neighbors. We should applaud states that lead on reforming drug policy. And, consistent with the Republican Party’s origins, we must demand equality under the law for all Americans. …

Marriage is not an issue that people rationalize through the abstract lens of the law; rather it is something understood emotionally through one’s own experience with family, neighbors, and friends. The party of Lincoln should stand with our best tradition of equality and support full civil marriage for all Americans.

This is both the right thing to do and will better allow us to confront the real choice our country is facing: a choice between the Founders’ vision of a limited government that empowers free markets, with a level playing field giving opportunity to all, and a world of crony capitalism and rent-seeking by the most powerful economic interests.
