Mark McKinnon, previous touter of Perry strength, finds Lone Star topper's debate perfs as inexplicable as others.

McKinnon: "Debates require a lot of hard work and preparation. If you try to wing it, it shows." "I gave Governor Perry a pass on his first debate. But I was really surprised at his second debate. And shocked by his third. Because he showed no improvement. At all. He should never have been surprised by questions on Social Security, illegal immigration, and HPV vaccinations. But he responded like he was hearing the questions for the first time. Even the third time he was asked."
