Decisive! (Again and Again)

An email from John McCain's campaign:

Tonight John McCain will once again take the stage with his Republican opponents and face off on the issues important to America. If the past debates are any indication, this debate will be another decisive night in which John McCain will stand head and shoulders above his opponents and prove that he is the only one who is ready to lead our country on day one.

How many more decisive nights are there going to be?
