At the recent local elections, that, as per general elections I previously received through the post a polling card: which is what one takes to the polling station to show to the people there who check on a list of names & addresses printed out from a database.
That being the Electoral Register.
It is compulsory to be on that: with a £1000 fine for anyone who isn't. Perhaps Australia has the right idea:
Making voting compulsory.
As well as being on a register of voters: periodically I receive a letter asking if I am at the same address or - if I have moved - the new resident for their name at that address. If they do return said letter with their new details, then said Register is updated, but if the original registered resident still lives there, then the letter says to ignore such and the Register is unchanged.
Which is why, last month, I received at the polling station a ballot from the people there which I took to a booth, marked with an 'X' (next to the Labour candidate, natch), folded and put in the ballot box there.
When the polls close at 10 PM said ballot boxes are transported to the count by the police who then ensure no external interference with the count once said boxes are opened for the ballots to be counted: that's why it's traditional for the winning candidate to thank the police for their part in the election.
Having to be on the Electoral Register. The security involved in the election process.
There. I've just destroyed your 'argument', Trumptards.
Evidence: I have that which proves ours works: so do the Democrats, as in the lack of such as far as your 'Opinion' is concerned.
