Rick Santorum will attend an Ash Wednesday service today, unlike Newt, so we know Santorum will receive ashes.
But there’s no rule about how long you have to keep the ashes on your forehead, so I don’t know if Santorum will wear ashes to the debate. I hope he does, and I’m guessing he will. That’s what I would do. To me, he’s there not just as a presidential candidate, but as a representative of all Catholics in this country.
