McCain Senile?

McCain’s enormous confusion over Zapatero/Spain really causes me to ask whether or not the man is mentally fit. He often seems to get confused in interviews, and seems truly unable to cope with unexpected questions (e.g., on The View), but I don’t recall him ever having not just misinterpreted the questions, but in this case, he couldn’t even absorb the clarification kindly offered him by the interviewer.

If he has more of these gaffes, I wonder whether he’ll be completely toast.
