I agree. Why should anyone care if the LDS faithful support one of their own and would like to see him succeed? Any other religious or ethnic group would behave no differently. It's embarassing to watch people deny the obvious, but I do understand the sensitivity issues the LDS church faces if it's accused of throwing its substantial weight around in the primaries.
I don't think we have "substantial weight" anywhere but Utah and Idaho. And Mitt wouldn't need a special organization in either of those states. Everybody knows he is Mormon. If the Mormons are inclined to vote for him because of religion, they will do that without any special organization. And, whoever is the ultimate Republican nominee will carry those states without any special organization.
