I think I know why Mitt Romney is so hesitant to release more of his tax returns

I’ve lived and worked around ‘card carrying’ members of the Mormon church — those with the temple recommend — for over 30 years. The only thing that I can suppose why those returns have not been released — IMNSHO — is that the LDS church would find out the Romney has not been fully tithing (contributing 10% of his income) to his church. *That* would be the only thing I can come up with that might cause him to behave this way. Again, In My Not So Humble Opinion. Otherwise why would he not just say, again, that “I paid *all* the taxes I was legally required to pay and not a penny more.”

Thoughts?
