It was just funny. You know that disclaimer lingo at the end? the pitch is over, and the voiceover says "this ad was paid by the super pac of whatever and ....40 more words," the part that goes so fast it's just about unintelligible? At the same time, the video shows Rubio at a podium, talking, and I swear, his lips looked like they were sync'd to the voiceover.
The opening of the ad was brutal against Jeb.
