The Romney issue begs a question:  How many people really go against the faith taught them by their family, particularly if their family is more or less unified on the subject?  I'd be willing to guess that in those scenarios, for nearly all religions worldwide, the percentage is very low.  One could argue that Romney (and many others) are almost trapped in a paradigm created for them. 

The bigger question is, of course, does coming from a different religion affect ones executive or legislative decisions to the point that they are untrustworthy to those who don't share a similar background?

In the case of Romney, I'd assume not but rather that there are more concrete political positions that are not favored by many on this board. 

I actually admire his business success and his outcomes in the SLC Olympics and as governor of Massachusetts.  But I've heard way too many dimwitted comments (chief among them:  "I'd double the size of Guantanamo") to consider him for the highest office.  That kind of ridiculous pandering makes him automatically disqualified in my book.
