They were having to be talked through filling in the form only to hit a roadblock when it came to proof of address. After expressing their voluble disbelief at some length that the handwritten doctor's note they had would not suffice, they eventually left empty-handed. (Incidentally, they were only looking the card to use it for ID for flying, they had no interest in voting).

Now these guys were obviously jokers, but it shows you will need a certain degree of application and time to get even the most rudimentary of verifiable ID. Even the conscientious may find themselves not getting around to getting the ID before election and losing their vote.
