Judging by the contents of the (occasionally profane) comments on youtube, however, it seems many people are not enjoying the humor here.
It's still an ad hominem attack, but at least it's funny. The samples of Obama's language here smack of gratuitous self-confidence. His speechwriters really should be more careful. Uttering such words is really an invitation.
The ad would carry more weight, though if there were more policy-based adverts out there to go with it.
