Awful - my Mum had it for years, due to being immobile and housebound - she always, always used her vote, a matter of deep principle for her. Neither did I ever take it and fill it in with my preference- I did know who she voted for as she said, but to pretend that chat can’t happen is disingenuous.
There will be many older folk who are conscientious about voting who would be dismayed - yet not enough to disrupt any vote, as most manage the completion themselves, and independently with privacy.
Not to mention the disabled - but we know Farage doesn’t like them already.
I so don’t want to live in a cosplay US with a cosplay Trump.
