I personally don't give a rat's behind whether Rand Paul is a young earth creationist or not. Because the age of the earth is not an appropriate subject for Senate action.
I think that the Kentuckians who asked him that question are a$$hats, for the same reason.
Creationists are not generally known for being Pro-Abortion, or Anti-Gun. Just doesn't "go with the territory".
So, to me, this is reassuring. But, no, it's not a subject for Senate action.
