Not to mention the Bible Belt refusing to vote Mormon whom every Bible believing church across the country will be giving sermons on the reasons Mormonism is classified by every Christian denomination as a Christian cult.
Every little bit that shows him to be a liberal will only be remembered by conservatives and Christians across the South and Midwest. No different for any Republican from liberal states only worse for Romney because of his Religion, and don't get me wrong, this same problem will come out if Obama wins the dem primary. While his past might be allowed to skate through a dem primary it will hit him with devastation in the general election if he really did grow up attending a mosque. Everything matters in a presidential election from your views to the basis for those views, your religion.
The people who show up for Republican primaries are very conservative.......Can somebody name for me the last time a Republican from a Liberal Northern state actually won the primaries, was chosen by those conservative Republicans not to mention went on to actually win the general election??
