A lot of people working on projects like that don't vote, or at least don't vote where they work.

Absolutely.  The last thing on these unfortunate people's minds is a senate election in the backwater in which they're serving time.  They serve time in these hell-holes for one pipe-dream - to save money to try to 'escape poverty' - they work obscene numbers of hours, live in horrific conditions, and don't have time to care about the locals voting.
