Well, that could be complicated in a region like ours, where we have elections running every two months. I could consider 15, maybe even 30, though. But you could easily work your way around that. Most parties know which candidates they're running months before the election. That would only make things a little more difficult for them, having to make sure everyone was moved to the right region within 45/30/15 days before the election.
I don't want to make it any easier for a Party to move people in before an election. While you have a valid point about the 2 month elections, nobody has strategically moved in order to win the Mideast Assembly or the Governorship of the Northeast. This is all about Federal Elections, which are every 4 months.
