WASHINGTON (Reuters) - Paul Ryan may have taken a punch. But Tuesday night was far from a definitive blow for Mitt Romney's hard-driving presidential running mate, a veteran of Congress who according to one admirer is "just getting started."
History hasn't been kind to losing vice presidential candidates. Only two have gone on to become presidents themselves. The last two failed running mates were Sarah Palin and John Edwards - one went on to a reality television show, the other's personal life turned out to be fit for a soap opera.
