One of the few genuinely interesting and original things I've read in the torrent of words pouring out about Gov. Romney's promise to give a speech about the so-called Mormonism issue, is Nate Oman's Thoughts from the Anvil: Mitt, Mormonism, and American Religious Politics. Go read it.
Unlike Oman, I sure don't have anything interesting to say. Personally, the man's religion is not an issue for me. (The lying and apparent plasticity of principles on the other hand….) The timing seems very tactical, a response to dropping poll numbers. It's a speech I think Romney would rather not give, since many GOP primary voters don't believe in the separation of church and state at all — they want the state to enforce morality and subsidize their faith based activities and perhaps even their established churches. The general election voter, on the other hand, is a more diverse and discerning breed, and not so willing to have protectors of the faith, thought police, mullahs, or whatever, patrolling the virtual and actual streets. But you knew all that.
