Either way, you'll get people from every region voting. I wouldn't put much personal stock in the polls.
Polls in Atlasia have never been very reliable. They're still fun, though.
I've heard that it is possible to revise the poll options, but I've never done it & I've also heard some people say that they couldn't. Make of that what you will.
I believe you can but there's no point in doing it here (because many have already cast their ballots and cannot switch their votes).
As I understand it, editing the poll options resets the vote count.
