I'm not so sure. I was against an amendment, for the reasons he states -- you don't tinker with the Constitution if you can possibly avoid it. But then this stuff in California happened -- the people charged with upholding the law are using their powers to ignore it. I've changed my mind.
I'm not even all that passionate an opponent of gay marriage, but I can't think of any other way to prevent 'public servants' from making up the law.
The problem is elected officials and judges making up the law as they go, and that can't be solved with this Constitutional Amendment. Maybe you should think about how you could create a Constitutional Amendment that would prevent them from making up the law, rather than an amendment to ban this one thing (gay marriage).
