But I agree, questions should be asked of the Mainstream Christian candidates if they've not already made themselves clear. I think most of us know what mainstream Christians are all about. Mormonism throws a few curveballs into it.
People's beliefs produce actions. I get the feeling Romney is not exactly the "obedience at all costs" kind of guy like he coventants to be in the temple. But if he takes the temple covenant of obedience seriously it would be good for us to know to whom he believes he must be obedient at all costs.
If he believes he should be obedient to God, the prophet, the apostles, his SP, his BP and so forth, then that's one problem. If he believes he should only be obedient to God, then the nature of his beliefs in personal revelation should be examined.
I think that's a valid issue for us to ponder that isn't likely to come up so much with a mainstream Christian.
Mormonism has not been vetted. Vetting is a process of examination and evaluation, generally referring to performing a background check on someone before offering them employment. Before offering employment to Mitt Romney his background, including his beliefs, need to be examined and evaluated to see if they're compatible with the responsibility of being given access to the world's only remaining superpower. If he is so unreasonable that he refuses to accept superior evidence contradicting his beliefs, then he's delusional and unfit for public office. Of course so are his 'Christian' competitors. Honestly I think that Mormonism cannot withstand the scrutiny of a presidential campaign, but it will be good to bring this most absurd, racist, misogynist and homophobic religion out into the street for examination. There is no better disinfectant than the broad light of day.
