It now seems possible that Dan Quayle's legacy will involve more than just his inability to spell root vegetables. On Fox News Friday, the former vice president under George H.W. Bush (who infamously added an "e" to the end of "potato," at an elementary-school spelling bee in 1992) announced that his son, Ben, has entered Arizona's congressional race to succeed retiring Republican Representative John Shadegg. "We are convinced he will be successful," the elder Quayle said. The junior Quayle is one of several political legacies who've recently announced their bid for office—including Chris Cox, a grandson of former President Richard Nixon, and Rand Paul, son of 2008 presidential candidate Ron Paul.
