Having grown up in a mormon enclave, IMO mormons will flock in droves to contribute to Mitt....and without any undue influence from church leaders. Rank and file mormons would see the US presidency as their due. They really DO see themselves as a "special" people.
"Mormons embrace the term “a peculiar people” as a badge of honour." See the following: Embodying the contradictions of ‘a peculiar people’
My LDS elderly mother is tickled pink at the prospect that "We just MIGHT have a mormon president!"
IMO, mormons might as well get used to hearing about Mitt's money coming from them, because it will be true and there are a LOT of mormons with a LOT of money to contribute.
