This time, with statistics! (Those make everything better.) All raw data come from the Election Results site, but the calculations thereon are mine, as are any transcription errors. I will also note up-front that there are a lot of factors in here, and in particular the electorate-level data do not necessarily correspond to individual voters, even collectively – the voting populations may be significantly different. They’re just interesting to look at.
