In the past hundred years, the U.S. presidency has veered more and more to the left — not in policy, but in handedness. Barack Obama is the latest to join a long list of left-handed presidents from the 20th century: James Garfield, Herbert Hoover, Henry Truman, Gerald Ford, Ronald Reagan, George H.W. Bush and Bill Clinton were all southpaws.
What makes lefties so electable? Some experts think left-handed people have a greater aptitude for language skills, which may help them craft the rhetoric necessary for political office. And as for the bout of recent left-handed presidents, some think it's because teachers only recently stopped working to convert lefties to righties at an early age.
