While Sweden/Norway/Finland is often cited most often when it comes to centre-right cities and centre-left country side there are other examples as well.
In Spain Madrid is centre-right while the rural Andalucia is left-wing.
Oh and as far Sweden goes, it's also worth noting that it's only Stockholm that's solid right of the big three cities. Gothenburg is won by the side that wins the election, and Malmö leans left and only go for the right when they win big.
I have always wondered why that is. I can see why Göteborg is solid for Socialdemokratarna, since there used to be a lot of industry in and around Göteborg. And with the industry come blue collar workers and trade unions, who vote for the parties of the left.
But why doesn’t this apply to Stockholm as well? Were there less of an industrial presence in Stockholm?
There's never been any major industry in Stockholm, it always been dominated by white-collar middle-class, while Gothenburg and especially Malmö on the other hand were historicly working-class cities with big industries.
