Will Mitt Romney's Mormonism be a liability in the upcoming election? Jane Pitt, mother of actor Brad Pitt, does not believe it should.

News-Leader in which she referred to President Barack Obama as a "liberal who supports the killing of unborn babies and same-sex marriage" and encouraged fellow Christians not to vote against Romney just because he is a Mormon.
