Wallace asked him about other situations, such as a former Arkansas governor’s unwillingness to enforce SCOTUS’ ruling on desegregation, or turning over required documents to Congress, a la Nixon. Huckabee seemed to say it the first was fine because the president, in that case Eisenhower, agreed with the ruling, which begged the question; in the second he said Congress can impeach an executive if he refuses to obey. So, all in all, adult ways to govern.
