Reduced role
Shortly after Luanne began attending college, her role in the series was diminished, almost to the point that the character was written out of the show (for an extended period, she did not appear in any episodes). This was due to Brittany Murphy's increasing popularity at the box office and her pursuit of a movie career. One prominent episode that came around the time of Murphy's temporary departure was a 2000 "election special" in which Hank encouraged her to become involved in politics so that she could vote for George W. Bush in the 2000 U.S. Presidential Election. During voter registration, though, Luanne was informed by a "lady in a poncho" that Bush ate puppies; Luanne took the woman on her word, and registered as a communist.
