"Well, ignoring the Mormon-baiting tone for now, what, exactly, does that claim have to do with serving as president? I mean, even if it is exactly as you say, why should that keep someone from voting for Mitt?"
In this instance, it addresses the poor race doctrine of Mormonism that Romney will have to defend. But in general, Mormonism has many far fetched claims that Romney will be repeatedly be called on to defend.
A catholic has to defend or condemn the abortion position of the Pope, as well as pederasty by priests, and a host of other issues. With Mormonism, you open an even more complicated Pandoras box of issues. Now, in an era when presidential elections are being won by 1%, AND Romney is by all rights a marginal candidate, do you really want to go down this road?
I have many other objections, search my name and you will find them.
Why?
Why is Mitt required to defend the LDS Church? Is the LDS Church running for president? Is Mitt running for Pastor of the United States?
Why, in this case, is a man's religion on trial when he's seeking public office? That question is simply baffling to me.
Unless you can demonstrate that his faith will somehow necessarily prevent him from honorably serving as president, or render him incapable of fulfilling the oath of office, I see no reason at all for it to even enter into the debate! It's completely irrelevant!
You even have lots of examples from which to choose! Find examples for me where an LDS official was unable to honorably fulfill his duties in elected office, or violated his oath of office because of his LDS faith.
I defy you to find even one case.
