Cambridge, London, Bristol. The same people who voted to stay. What a surprise.
It isn't the hard core that win elections, its the swing voters. So no it isn't a surprise, and it isn't really relevant.
The question is, is this a metaphor for the govt and country, or the website struggling under the weight of traffic.
Ps I live in a probably leave voting area, so please don't tar all people with the same brush. >50% voted against remain, so calling them all less intelligent isn't helpful. We do have to get on again after this after all, and if there is a 2nd referendum, they might respond better to addressing their actual concerns, rather than insults.
