The Beltway people are terrified of Palin and Jindal because they are not insiders. When Reagan came in he got rid of a lot of old FDR holdovers and really shook up DC! No one had done that before. They want to make sure that never happens again. Republican insiders or Dems have been in charge since 1932 (except Reagan) and they want to keep it that way.
Reagan did not remove old liberal holdovers. He hired James A. Baker, III, and Michael Deaver, who undercut him for years afterwards.
