One question Lindsey Graham shouldn't have to answer: Why are you still single?

Sen. Lindsey Graham's best campaign isn't his bid for the presidency -- it's the one he's waging for single Americans.The snark and questions he's getting about his unmarried status are ones that singles encounter every day. Senator, I know you're not in this race to battle the stigma against being single, but you're doing it anyway. And it sure is needed.
