It’s all in the editing.

Say what you will about Rick Perry, whenever I see one of his attack ads I have this incredible urge to rewatch Transformers.

I was going to watch his most recent ad attacking Mitt Romney’s health care plan, but I kept having seizures. Or maybe it was just the ad.

“You could make a pretty good ad by just stringing together all the ill-advised sound bites Mitt Romney has unleashed in the course of his nigh eight-year candidacy,” someone pointed out. And Rick Perry’s team seems to have noticed. That’s what this ad is — a string of Romney gaffes from the vintage “I like mandates” to the more recent classic “There are a lot of reasons not to elect me” — put together by someone with a short attention span who would have preferred to be making an apocalyptic vampire action film.

It’s another instance of Petri’s Law — anyone allowed to talk long enough without interruption will inevitably make a career-ending gaffe. Mitt Romney has been allowed to talk longer than almost anyone on the podium, except for Newt Gingrich whose campaign was over before it began. So, inevitably, he’s made some gaffes. Just string them together, pipe in the ominous music, cut to a few Change signs, and let the audience’s imagination do the rest. Sure, Perry is gaffe-ing to beat the band, but add a little thunder and some creepy mirrors and see what happens.

This is worse than the trailer for Fight Club.

Based on the ad, I assume that Mitt Romney has been Barack Obama all this time!

Or Tyler Durden. Or both! All I know is, I’m not going to buy any soap from the man.

It’s the magic of editing. It turns out that the most effective case from Rick Perry against Mitt Romney is one Mitt Romney made on his own, just to demonstrate how it was done. Romney certainly does a better job of attacking Romney than Perry did at the last debate.

And then a few flourishes — thunder! darkness! mirrors! — and we’re sold.

If Rick Perry himself were this easy to fix in post-production, he’d have it in the bag.
