Santorum, in contrast to Gingrich and the others, has become a person in the minds of many, and not a politician. His daughter’s illness, among other factors, mean he is looked on as a caring person. Mitt might find that the usual slime dog won’t hunt in this case. It could easily backfire.
THe same thing happened to Palin..in fact, it amplified the attacks.
Let Romney do his thing. I hope Newt holds back.
