Which is why he should spend time with this daughter.
I'm not going to try to pretend here that I really understand Santorum's thinking.
To go into some background, I lost both of my parents to cancer at a relatively young age. At that time, I worked two part time jobs, was in the National Guard, and was taking college courses full time. And I tried to keep busy with those other things because the more serious thing was really too much to deal with at 19.
I personally wish I had spent more time with them at the end. I just can't see why Santorum is continuing at this point. He should hang it up. No one would think the less of him.
