Does McCain keep meaning to say WHEN I'm elected and screwing up and saying IF I'm elected?

[complain jane]

Because every time he's at a rally lately he says "My friends, if I'm elect- WHEN I'm elected President..." and then he turns around and seems to look at Cindy and seems really pissed off for a second. Yesterday he did it and when he turned around he muttered something to Cindy. It was kind of like the Aricept commercial where a spouse says "John was diagnosed with early onset Alzheimer's, but I decided to wait and see how he does. Then at his rallies he kept forgetting what the hell he was talking about- I knew then it was time."
