Summary

Since the voters cannot be changed, the users unable to vote cannot be replaced, and after a certain amount of time, there would be no users left who can vote. This would lead to the contract being unable to conduct elections.

Vulnerability Details

There should be a function to add new voters in order to make the contract feasible to use for an indefinite amount of time.

Impact

Contract would not be able to conduct any elections after a certain amount of time has passed.
