I have never understood why, but Elections Canada goes to the parties that came first and second in a riding to find their staff at the polling stations in an election. The returning officer for each ridings gets lists of recommended people from the top two finishers in the previous election.
What I do not like about this is that it means the majority of the people working at the polling stations have strong partisan leanings. It strikes me as a bad idea because it places too many people in a position of temptation and someone of them are likely to act. I have seen this in action when the polling clerks are doing the counting.
This is a bit of the old patronage thing that is still around. A chance to reward your supporters with some work. It just seems so utterly wrong.
In all three current by-elections only the NDP and Conservatives will be allowed to forward names for people to be Deputy Returning Officers, Poll Clerks, Information Officers, Registration Officers, and Central Poll Supervisor. The conflict of interest seems to clear to me.
