how can we know what he is up to. If he's doing the back door diplomat bit he has to maintain his clueless dolt always heading for the surf and sail bit . . . but he can pass between both worlds so Trump would use him if Kerry would agree and . . . well we really can't say what the dude is doing. The world that he was part of was as a cousin, without inheritance. So he's clawed his way forward anyway, and tried to be something even though he didn't get a stack handed to him. He had to go and take it.
That's the story he'd probably like you think it is.
My guess is that if he's doing anything as a pretty boy messenger to his creepy ancient cousins then he has to do it as if it's not from the diplomat core.
