At a gathering of friends before the 2008 election I once stopped an Obama debater in his tracks. Shut him completely down for the rest of the night with one simple question, which was:
"Without using the words 'hope' or 'change,' what is Obama going to do?"
This "huge" Obama supporter (who is also usually quite knowledgeable about politics) quickly realized that he had no clue at all about the guy he was supporting & promoting.
"Hope & Change" rah rah rah!
And on that note, I think this might be in order: http://www.youtube.com/watch?v=zhhkF3dqXR0
