People didn't hold Ted's father against Ted because Ted's father's views were not his own.
People aren't holding Romney's father or grandfather against Romney, they are just afraid that he will govern according to his religious beliefs, which they disagree with.
Even though I'm not a Mormon, I personally would like Romney more if he governed more like a Mormon!
I would have like that too, but if he had, he would have accomplished absolutely nothing in the dem controlled Mass. What he did do, and the battles that he picked tells me he can win against Shrillary.
They can rest assured.
Romney did not govern "according to his religious beliefs" in Massachusetts. (Mormons are against same-sex marriage and abortion. As governor of Mass., Romney supported both.)
