Whatever you or I think about exclusive supplier contracts, is there a single state that forbids them except for unions?

Seniority rules are something unions negotiate for. Contracting firms stick warm bodies on projects all the time. That's between the supplier and the customer, not imposed by the federal government.

I agree it would be better to fix that, but as you said, it's a stretch. Good luck getting Republicans or Democrats to go for it.
