Priebus stuck with Trump when quite a few "establishment" Republicans turned their backs on the nominee. Not only has loyalty been rewarded, but Priebus is well qualified.
He also named Steve Bannon as chief hatchet man and attack dog. Now, that is not what his official title is, but that is what is job will be.
Both are great choices.
