One of the more popular indyref illustrations circulating on Twitter points out that Scotland has voted Tory for 6 years out of 68 but has had Tory governments for 38 of those years.
When you look at how Scotland voted and the resulting UK government, Scotland got what it voted for 54% of the time since 1945. However, this actually makes it sound like Scotland has a decent amount of influence. An analysis by Wings over Scotland showed that "for 65 of the last 67 years, Scottish MPs as an entity have had no practical influence over the composition of the UK government," and the conclusion was stark:
The truth is that the only people who can vote the Tories out are the English. It doesn’t matter what Scotland does: we get the government England votes for every time, it’s just that sometimes – less than half of the time – our vote happens to coincide with theirs and we feel as if we played a part when actually we didn’t.
This made me wonder how Scotland's voting patterns compare with the three Scandinavian countries -- Norway, Sweden and Denmark -- so I created an illustration of the largest party at general elections in Scotland as well as the political alignment of the governments in London, Oslo, Stockholm and Copenhagen.
Denmark is an even worse match than Westminster (Scotland and Denmark overlapped for 53% of the time compared with 54% for Westminster), but Norway is a much better match at 63% and Sweden topped this comparison with an overlap of 69%.
That's right -- for 69% of the years since 1945, the Swedish government in Stockholm has been in alignment with the wishes of the Scottish electorate, in spite of the fact that Scotland sends no representatives there.
This is not an attempt to argue that Scotland should form a political union with Sweden instead of England (although the government of the United Kingdom of Sweden and Scotland would probably act in accordance with the wishes of the Scottish electorate much more often than Westminster does). However, it's important to realise that Scotland influences the composition of the Westminster government so rarely that the government overlap with independent but like-minded countries like Norway or Sweden is actually much greater.
Being in a political union with a country that is ten times larger and has very different voting habits doesn't lead to a sense of enfranchisement in the population. Fortunately, the solution is simple: Independence.
