I hadn't seen the Monday Night Football where Barack Obama gives an introduction, but the following video annotated by Slate.com is fantastic:
I especially like the James Bond reference. Here is the segment from MNF without the annotation on YouTube.
I posted this because the annotated video is very funny IMHO and this is perhaps the best political ad I have seen in years. No mudslinging, make your candidate presidential, and keep him human at the same time. I can think of no other current politician that could have pulled this off. No wonder people are falling over themselves to get this guy to run.
