“If Dick Lugar,” said John C. Danforth, a former Republican senator from Missouri, “having served five terms in the U.S. Senate and being the most respected person in the Senate and the leading authority on foreign policy, is seriously challenged by anybody in the Republican Party, we have gone so far overboard that we are beyond redemption.”

Welcome to the party Mr. Danforth. However a challenge to Dick Lugar is a symptom.

Your party is already beyond redemption.
