This is precisely what must be done and one of the biggest mistakes of George W. Bush was not doing it. He basically just put in his own cabinet and left most of Clinton's political appointees in place.
To heck with that!
Every single Obama, Clinton and Bush political appointee must be identified and slated for immediate replacement after the inauguration. Cain should start planning for that right now by assigning at least two qualified staffers who will do nothing but identify targets and locate qualified replacements.
Then there are all the Executive Orders that Obama has been flinging around, not to mention a huge number of Clinton's that Bush let slide. Another two staffers should be tasked with reviewing all of them and targeting any that are suspect for immediate nullification. "Stroke of the pen, law of the land"? My a$$!!!
What one President can appoint/impose, another President can replace/rescind.
No mercy, no arguments, no appeals. Get rid of all of them. If you were appointed by Obama or Clinton, you're gone. If it's an Obama or Clinton EO, it's trashed.
End of story.
The Republican establishment exists only to get people elected with an (R) after their name. It does not exist to implement a return to Constitutional govt. Once the Pubbies are in power, all the investigations of criminal conduct by 0bama, Holder, etc. (Fast & Furious, New Black Panthers, birth certificate fraud, etc.) will stop. We need an outsider who will push the war until the guilty are destroyed and made an example of. We need to put a stake through the heart of the commie beast, or it will rise again.
