Clements, a former Doña Ana Republican Party chairman who's running a libertarian-minded campaign, and Weh, a former gubernatorial candidate who has more money and more name recognition (pictured below), are in the midst of a heated primary battle. Both are fighting hard for party delegates, who will cast ballots for either Clements or Weh at Saturday's state Republican Party pre-primary convention. Each candidate needs at least 20 percent of the delegate support to get on the ballot for the June Republican Party primary election, when voters select one to face off against Udall in November. More than 50 percent of the delegate vote on Saturday will give one of the candidates top ballot placement in the primary.
