You got that right!
As a former salior, once-stationed in Mayport, I think I can safely say that this decision will not be a military one. It will be purely political.
Having visted Mayport as recently as two years ago, I can say that introducing a little more "military money" into the region would be good for their economy. The area has really gone to waste since I was stationed there in the late 80's and early 90's.
The the defense budget not the North Florida economic stimulus budget. That half a billion could be better spent covering some of the maintenance that's being deferred.
