Research into what was mainly an anecdote about my mum? Bit late and all available information on that was shared!
Research into the fact mainly older/disabled would be upset to lose their vote - obviously it is those people mainly who can’t get to the polling stations, and why should they not have a vote because of this, you didn’t say?
I guess you mean postal voting in general is an issue, but it would be helpful if you had shared the problems you see with it, as is usual on discussion sites - it would then allow me/us to understand the specific points and allow us to agree/disagree from there on the reasons for taking the quite ambitious (and scary) step of effectively removing peoples’ votes.
Thanks to @Notonthestairswe can all now see relevant evidence and none of it changes my support for it, or brings in a massive revelation showing old people should have no right to vote once they can’t get to a polling station, so I’m none the wiser still to be honest about your meaning.
