Candidates are entitled to change their minds, but Sharpe seems to change  his entire persona from one campaign to the next. Four years ago, when Sharpe  first challenged Gibbons, he ran as an independent-minded moderate. Two years  ago, he ran as a Newt Gingrich clone and attached himself to the House  Republicans' Contract With America. This time around, Sharpe seems to be  vacillating between those two identities.
