I attended the training session to become a poll clerk yesterday. It was good fun. Most other election staff are much older, perhaps in their mid-50s. But there were two who were probably in their early 20s.
It seems fairly straight forward. Greet the voters as they come in. Ask them their name and address. Ask the two official questions: "Are you the person registered in the register of electors for this election as follows (read up their entry in the register)" and "Have you already voted here or elsewhere at this election otherwise than as a proxy for some other person?". If they answer correctly, then they must be given the ballot paper. Stamp it first, then make sure they put it into the correct ballot box. Say thank you and DONE!!!
There were also some discussions about how to deal with difficult voters, polling agents and tellers. But nothing too difficult to understand there either. Ensure they behave properly, or otherwise get the Presiding Officer to instruct the police to arrest them. Simple.
But one thing for sure is that it will be one very long day. Start at 6.15am and finish at 23.00 pm.
