Screw them orders
, i would take the Enclave Personnel that dont wanna move west and head north to Alaska.
And there is absolutely no indication that any Enclave citizens would have thought that way, they'd probably be relieved that one of highest people in the Richardson administration survived; besides they don't really have a choice in the matter, if you tell the President to [censored]-off and splinter off on your own you aren't Enclave anymore - just traitors.
I still don't see why anyone wouldn't want to go, aside from the fact that I don't believe that anyone would doubt the President anyway, the Enclave really know [censored] about the mainland and would likely want to stick together for the sake of loyalty and comradeship.
