Unless……unless you hold your nose and re-register with whatever party owns your district. This holds true, whether you’re a Democrat in a Republican district, or vice versa. If your district is gerried to contain mostly Republicans, then it should be represented by a conservative person. But, as someone living in the district, you deserve to have some say in which conservative it will be! A Tea Party radical? Or a genteel negotiator, like Goldwater or Buckley?
