Here's Jon Huntsman in The American Conservative, telling his fellow Republicans to support gay marriage:
..conservatives should start to lead again and push their states to join the nine others that allow all their citizens to marry. I’ve been married for 29 years. My marriage has been the greatest joy of my life. There is nothing conservative about denying other Americans the ability to forge that same relationship with the person they love.
All Americans should be treated equally by the law, whether they marry in a church, another religious institution, or a town hall. This does not mean that any religious group would be forced by the state to recognize relationships that run counter to their conscience. Civil equality is compatible with, and indeed promotes, freedom of conscience.
That's Jon Huntsman, everybody: A good human being, a sensible politician, a smart policy guy, and—according to other Republicans, anyway—the worst Republican on earth.
