The latest addition to President Obama’s stump speech, debuted Friday in Virginia, is a running schtick about Romney’s Etch-a-Sketching ways. The coinage Romnesia–a combination of Romney and amnesia–and the Jeff Foxworthyian delivery are pretty funny, even if the critique that Romney is simultaneously an unflinching ideologue and a fair-weather flip-flopper doesn’t make a whole lot of sense. Stump speeches aren’t the kind of stuff that really affect elections, but give this one a watch. Two weeks ago at the first debate, Obama looked like a sleepy hostage. Now he’s having fun.
