Every presidential election cycle, once a party’s nominee becomes clear, we focus on the veepstakes. Who will Mitt Romney choose? Will he play it safe with a traditional pick, such as Walter Mondale in 1976 or Jack Kemp in 1996? Or take a chance, as John McCain did with Sarah Palin in 2008? Either way, there is no evidence that a vice presidential nominee plays a great part in voters’ decisions. But that doesn’t stop us from overhyping the selection process.
