There is an article in the current Newsweek about Mrs. Santorum living with a much older abortion doctor when she was in her twenties, before she married Rick Santorum.

There were a couple of FR threads about this. I couldn’t find the FR threads using the search function.
After reading that article you linked, my opinion of Rick Santorum just went up! I never considered voting for him, but the fact that he married a woman who herself had not lived a perfect life previously, and together they changed their lives to commit to marriage and family, is not a negative thing. In fact, a story like that one shows that he’s not the “self-righteous, sanctimonious” person people make him out to be.
Now, if Rick himself had been the one living with the abortion doctor, I might see it differently...
