Summary: Aubrey Immelman, director of the Unit for the Study of Personality in Politics at St. John’s University in Minnesota, said Mitt Romney may be overcompensating for his inability to connect with regular people. “Romney is neither an introvert nor an extravert,” said Immelman. “The key is his conscientiousness. People who are highly conscientious are just not good campaigners. He might be a good executive, but campaigning is his Achilles’ heel.”
