Mormon's stacked the audience during the debate and whooped and cheered at every Romney platitude. They are a big factor and likely vote more Republican than Democrat (Harry Reid excepted). In fact, the Mormon temple in Mesa has the biggest attendance of any outside of Utah. The LDS population in the PHX area has led to the building of two more temples that will open in the next two to five years. If Santorum can cut Romney's lead or even defeat him there (as unlikely as it seems), Mitt will have trouble going forward in areas less populated by them.
Well, they said that the Mormon population in Colorado would hand Romney the victory, but it didn’t work. So, maybe there is hope.
Are you aware that the University of Phoenix is a Mormon company and that they have been under attack from the Obama administration?
