From “Turnaround” to Etch A Sketch: Above, the original flip-flop ad, used in 1972 by “Democrats for Nixon” against Sen. George McGovern. McGovern wasn’t really a flip-flopper, he was a consistent liberal. This year the Obama campaign has chosen to portray Mitt Romney as a “severe conservative” (his phrase) rather than as the flip-flopping Etch A Sketch (Romney’s top advisor’s phrase), on the theory that voters don’t mind a flip-flopper - it can even reassure them to think the candidate won’t really do everything they’re afraid of. But the Romney who showed up for Wednesday’s debate has been flip-flopping all over the place, denying his plans to give $5 trillion in tax cuts or cut off coverage for pre-existing conditions, and even taking back his “47%” comments in an interview after the debate. Of course, President Obama never called Romney out and let all his flip-flops go unchallenged, a mistake President Nixon would never have made.
