I'm a fan of negative advertising. I think there's nothing wrong with pointing out how you're different from your competitors. Sometimes that means you highlight how awesome you are. Sometimes that means you highlight how bad they are.
People claim they don't like negative advertising but compare Newt Gingrich's standing after he won South Carolina's primary with his standing after Mitt Romney and his supporters ran $20 million in negative advertising against him.
Still, people complain about negative advertising and say that it's ruining the Republic. The best response to this? Reason's video showing how nasty politicians were circa 1800.
The conventional wisdom is that Romney has to be careful in how he goes negative on Rick Santorum. I almost wish he'd be careless. But, then again, I enjoy negative advertising.
But look who has a negative ad out against Romney! It's Santorum. And it's funny. So maybe that should be the strategy: if you go negative, at least have the decency to be funny. Check it out here:
