Rick Santorum's new anti-Mitt Romney ad is quite good.

The imagery is so funny that you barely notice the weak citation. Two lines: A claim by Rush Limbaugh that Romneycare was Obamacare's blueprint (Santorum's ads often quote Limbaugh), and a claim in USA Today that Romney's ads may hurt him. Never mind any of that! Instead of responding in kind, Santorum -- who has won less than half as many votes or delegates as Romney -- portrays him as the kind of desparate oaf who'd shoot a paintball gun while dressed for a power lunch.
