I am currently homeless and chronically ill. I looked into trying to register to vote locally for U.S. elections last fall. I am registered to vote elsewhere, but failed to get registered locally (gave up when it became clear it would be too late).

The assumption that you can manage to fit voting into your life comes from a place of privilege that some people lack. Punishing them harder until they behave more responsibly fixes nothing.

I'm sorry you're homeless and chronically ill. I was talking about people in the UK though, I'm aware it's difficult in the US but to my knowledge the UK is much different.

EDIT: It appears the UK has some problems too [1], and being Australian where voting is a legal requirement, easy to enroll and difficult to drop off the register, my perspective is perhaps a bit harsh.

So is the argument that Remain would have won had it not been for the physical state of the voters?

I'm sorry to hear of your situation, but I hardly think it's relevant to the discussion.

What interests me is that, despite that example, folks across the pond made exactly that mistake in November! Maybe we truly can't learn from others' mistakes.
