Clinton got rid of everyone, even those beyond the travel office. My 1st cousin had worked for the phone company in the White House since Nixon. He was let go too.
That seems to be the MO for the Rats. Here in NM in 2003, new Governor Richardson fired (aka "demanded resignation letters from") every non-civil service employee in every department and division, every member of every board and commission (from hairdressers to professional engineers), every judicial oversight board (until the judges stepped in), and every member of the boards of regents at state schools and universities. The excuse given was so that he could shape state government to better govern and serve the public. Even some members of the press felt a little uncomfortable swallowing that excuse. If the Republicans had done that, they would immediately have been assailed as "right-wing, partisan and mean spirited". By contrast, the previous eight years under Governor Johnson could be described as "benign neglect". If things were going good why change them? The republicans have to bite the bullet when taking office -- clean house and kick out the SOBs. Let them bitch to the press at the beginning of the administration not at the start of the re-election campaign four years later.
