Credibility? What Credibility?

Political advertisements on both sides of the aisle often strain credibility. It can be tough appearing humble when you have the drive and determination necessary get within a couple of hanging chads of being leader of the free world. But what does it say about you when you place paid advertisting proclaiming yourself the winner of a debate that hasn't happened yet ? I think Chez at Deus Ex Malcontent has the question right, but whether the source of problem lies with the candidate or his organization the fact that the advertisements ran reflects very poorly on the candidate's credibility and capacity to run the nation.
