How do you explain all the ethical questions about his activities while in office ?
Poor judgement, naiveté, inexperience, stubbornness, etc.. He has made some minor mistakes in his career. But he's smart and he's a fast learner. I think he'll avoid making those mistakes again. (He'll make new ones!)
One of his best qualities is also one of his worst: his loyalty to his staff and friends. He's like President Bush with Alberto Gonzales, for example.
One other point about the ‘ethical questions’ -
Some of his mistakes were his own fault, but a lot of them were manufactured by the opposition. We do have leftists in Arkansas, and they have relentlessly attacked Huckabee.
