What’s your presidential candidate’s sign? Depends on who you’re looking at. In the case of Rick Perry, it’s a calm, confident and collected signature, befitting of a longtime governor. In Barack Obama’s case, it’s showy, with giant letters for emphasis. In other cases (Herman Cain, ex-candidate Tim Pawlenty), the candidates sign it like a doctor might — ironic, considering the actual doctor in the campaign, Ron Paul, has a clean signature himself. Check out the signatures that Buzzfeed gathered. They’re pretty interesting.
