Karen Santorum is not as often on the campaign scene...(ask any reporter) because as heart of the family she is home with the younger children and little Bella.
And they have round the clock nursing which they pay out of pocket....because of Bella's special needs.
I don’t think it is hitting low wondering about Bella.
He wears the pin, it is noted on his campaign hand-outs, those things just punctuate her absence with the constant fan of family behind him. We know she is sick and all of that makes me think about her.
As a parent (yes, I know all parents are different) I wouldn’t bother with running for president if I had a child with a limited life expectancy. That’s a personal opinion on what i would do.
If you see that as hitting low, so be it.
