IMO, Romneys religion is a valid issue, it determines his worldview and the culture and frankly, also affects his political stances and his flip flopping.
I certainly respect your take on Mormonism reaganaut, and sometime would like to know why it would have bearing on his politics and flip flopping. LEADING with that as a criticism though is bad politics, IMO. The majority of Americans have scant understanding of Christianity, far less Mormonism. Few care, in what is frankly a witlessly apostate general population. I just don’t see the percentage in choosing that as the principal point of attack when so many other approaches are easier and will have more resonance in an anti-statist atmosphere.
There is certainly many other reasons to not vote for (or vote against) Mitt, but it concerns me that there are people who buy the propaganda so easily. For me, and many others, Mitt’s religion is an issue and it will be a major factor if he gets the nomination. It is better to be prepared, IMO of the arguments that will be presented.
