McCain now seems to think Gen. Petraeus is chairman of the joint chiefs. You would hope that, as president, he would know who to call when a war breaks out.

Look, nobody is perfect, but war and foreign policy are McCain's best subjects, according to him, and he keeps messing up. He can't tell the difference between Sunnis and Shias, doesn't know that Iraq and Pakistan don't share a border, claims he never said the word "timetable" when he's on video doing so, etc. etc. etc.

But when will the big media outlets start to question his competency to be president? John McCain could claim to have dug the entire Panama Canal with a spoon and reporters wouldn't ask a question.

Maybe the Democrats are holding their fire on McCain until after the GOP convention, so there's no chance of them finding a replacement.
