I have always been in support for a decentralized system for all sorts of spatial data collected and used for electoral processes, be it US or a developing country as mine, Pakistan. A decentralized system would eradicate the possibility of political control by any entity during this important process (elections) in the form of rigging.

It might sound hypothetical and subjective, but I believe no electoral process (developed or under-developed parts of the world) is without the control of institution(s) having high stakes in the outcome of the elections.
