Re: The IP address is not a great way to decide validity
Funny definition of gerrymandered.
You miss the point.
The whole point of the referendum was to deal with the Tory party split. So many things were gerrymandered in favour of the maximum Out vote, so they'd have the maximum lack of credibility crying Foul.
Hence gerrymandering the electorate, the date, and the terms of debate.
Hence "negotiating" that worse-than-useless pretend-two-wrongs-make-a-right deal.
Everyone saw it as an internal Tory party row, which of course wrong-footed most of the non-Tory-party population and the rest of the world. Even the electoral commission played along, appointing the Tory Out faction rather than the Faragists as the official out campaign to keep things within the Party.
