For me it is the concept of registering to vote. I am citizen so I have the right to vote automatically and only thing I need to provide is some accepted ID.
Yes. In the UK, our elections are always on Thursdays. No one has ever complained about it because it’s literally not an issue.
The idea that it’s an attempt at disenfranchising people because you have to vote either before or after work is laughable.
The difference I suspect is in the ease of which we have access to local polling stations within walking distance of our homes, and how short the queues are, if there are queues at all.
In the US these problems can be magnified, especially if everybody is trying to pile in to the stations (or just reach them) within the one hour they have before their 12 hour shift, etc.
