Vertigo and his awesome avatar is right here. I seriously doubt the President was briefed on the specifics of a potential USMC uniform change.
To be honest, I don't think the President has a clue what HHS is even doing with all their problems, must less a hat change. He doesn't seem to get involved with the details of many specific actions and then acts surprised when something isn't going right...Fast and Furious, IRS issues, Benghazi, Pentagon suspending death benefits, on and on. I think it's somewhat by design--if he doesn't know about it, then he can say it's not his fault. Everybody in the administration seems to be blaming the contractors for f'ing up the whole Obamacare website rather than taking any responsibility themselves.
Standard politicians on both sides...but hey, we have the best politicians money can buy! Though it's a fun topic for a BO forum, I think the USMC hat is the least of our problems, including for those in Corps.
...but yes, the hat does look pretty gay.
