Former President Bill Clinton sounded frustrated about his value to his wife's presidential bid on the campaign trail in South Dakota on Friday. The ex-president took a moment to ponder his lot in life onstage, and revealed the exasperation he has experienced stumping for Hillary Clinton. "I sometimes feel that I'm totally useless in this election season because I'm a happy grandfather. I'm not mad enough at anybody," Clinton said. "And because the life I spend now is driven by the real world and facts. I mean, we live in kind of a fact-free political universe, you know?"
