The Offensive John McCain

We all knew that John McCain was out of touch about the Iraq war, but this is ridiculous. At a Concord, New Hampshire high school on September 4, 2007, the 71-year-old Arizona Senator was asked "If elected, you'd be older than Ronald Reagan, making you the oldest President. Do you ever worry that, like, you might die in office or get Alzheimer's or some other disease that might affect your judgement?"

CNN reports that after making a self-deprecating joke and describing himself as a "24/7 worker," McCain ended by asserting "thanks for the question you little jerk, you're drafted."
Doesn't this guy know there is no draft? (And wasn't this in some form a predictable question, which the elderly McCain has been asked before?) Really, if we had a draft, the response still would be inappropriate to the question, obnoxious, and offensive, but also almost somewhat amusing. With none, the comment is merely inappropriate, obnoxious, and offensive, and not remotely amusing.
