Term Limits is a sticky wicket. In one way I can see it, but in another leery over it. You lose continuity and knowledge.
That is why the USCG created the Civilian Search and Rescue Controller job, GS-11 and GS-13. Too many people
were being transferred out in 3 or 4 years and there was a loss of skill and knowledge. So it is a very tough issue.
As for Cruz being offered the position? I think he might just be honored for having it offered graciously to him.
Who knows?
