Defensive Obama Feels Need to Give an "I am a Patriot" Speech

Only a man who knows that he falls short in a certain area would feel the need to deliver a speech on the subject in an effort to shore up his credentials. Think Richard Nixon and his "I am not a crook" speech. Such was the case today when Obama delivered his "I am a patriot" speech; Or rather his "I am not unpatriotic" speech. Can anyone imagine McCain needing to deliver an "I am a patriot" speech? That contrast alone should be enough to give anyone pause.
