Post your elitist, "gotcha" commentary on the debate between Sarah Palin and Joe Biden below. Will either candidate defy expectations? Will Palin meet them in spectacularly mockable fashion?

Our commenters, of course, are bound by no such pledge. You'll probably want to view the thread with newest posts first. Or for a faster skim of the hottest topics, look at the most active discussions.
