  <blockquote>
    <p>Tags allow multiple selections - so they may not be appropriate for mutually exclusive characteristics (e.g. "Democrat", "Republican", "Green Party")</p>

  I don't think there is any way you can do this using Tags or Groups. The alternative would be a custom field of type radio, and then build Smart Groups off those options.
