You might be able to squeeze that polling place through the "temporary wiring" loophole. It would require GFCI tho. 590 is really somewhat poorly written since it mostly addresses wiring during construction but it acknowledges Christmas lights are included and we all know the NEC goes on vacation at Christmas. I just see Chevy Chase on a ladder with his T-50, stapling lights to the eaves and remember seeing that going on every December my whole life.
As for "mission creep";
I do agree the manufacturers have way too much power in the CMPs and that leads to abuses where they are simply using the code as a marketing tool for their latest invention, even when it is still an untested design.
