I didn’t think it existed.
It exists. I just didn’t save the source. Sometimes I do but mostly as I’m doing research just for myself, I usually don’t bother.
There is information here on FR about Santorum and the source article is here somewhere. Frankly, the more I discover about Santorum, the less I believe him suited to be President.
Sorry, but I can’t help you with a source.
I’m going to bed as it is late.
