How extreme is too extreme?

I think the Republican Party may have found it. When you have people like Pat Robertson, the man who said Hurricane Katrina was God's way of punishing New Orleans for the existence of homosexuality, using his platform on the 700 Club to say the party is going too far into the bushes, you know for sure they've slid over the line into Total Crazy. As Terence Heath noted,

If having Peggy Noonan as the voice of reason is like having Courtney Love show up at your intervention, and having David Brooks as the voice of sanity is like having Charlie Sheen offer to drive you to rehab, then having Pat Robertson attempt to talk you down from the ledge may be a bit like having Keith Richards as your rehab counselor.
