If I were a defense contractor, I'd follow the law, as written, to the letter. Even with some holy exemption from the Won, I'd follow the law, as written. It just isn't worth my business to have the gov't promise one thing, then have the NLRB sue me after O loses. And I could completely see him having the NLRB go after every defense contractor if he loses as a means of damaging as much of our security as possible, just out of spite.
