That has been in spite of blue-bloods like McLaim. It’s the rest of the non-annointed Navy that makes the Navy run as a successful entity.
I’ve known about McCain’s fitness as a Naval aviator for a number of years. During my military career I’ve seen the “legacy” officers who were given the desireable jobs and promotions because of who their father or grandfather was and who were as clueless as the day is long. He’s a fraud who has always felt he was entitled. I served with another officer who was personally a great guy but who had 4 DWIs, one while on duty, to his credit over a 20 year period. This person was still promoted all the way along to the rank of full colonel because of who he was connected to.
