One outcome of all the MySociety work for this election was the survey administered by DemocracyClub volunteers to all candidates. The results by party are graphed here, with standard deviations and error bars.
Some immediate conclusions: Surprising egalitarianism. Look at question 1, which asks if the budget deficit should be reduced by taxing the rich. Only the very edge of the error bar for the Conservatives touches the 50% mark; the only parties who have any candidates who don't agree are the BNP and UKIP. Also, question 4 ("It would be a big problem if Britain became more economically unequal over the next 5 years" - agree/disagree) shows that there is a remarkable degree of consensus here. The three main parties of the Left - the Greens, Lib Dems, and Labour - overlap perfectly, and even the lower bound on the Tory percentage is over 50%. Only the 'kippers and the fash even skim the 50% mark at the bottom end of their distributions. This may actually not be a statement about far-right thinking, because of...
Extremist internal chaos. On every question except the one about immigration for the BNP and the one about the EU for UKIP, these two parties have huge error bars for every question. As soon as they get off that particular topic, the error bars gap out like the bid-offer spread in a crashing market. Clearly, they agree about very little other than their own particular hate-kink. So the result in my first point could just be because they always have the widest standard error and deviation.
Immigration, or a field guide to identifying British politics. If you're a Liberal, Labour, or a Green, you've got no problem with immigrants. Even the upper bounds only just stroke the 50% line. All the parties of the Right, however, overlap around the 80% line. Need to identify someone's partisan affiliation quickly? Wave an immigrant at them. The other culture-wars question about marriage is similar, although the gap is smaller and the error bars bigger.
The consensus on civil liberties. Everyone, but everyone, thinks there are far too many CCTV cameras about. All parties overlap at between 68-78%...except for Labour. Labour is the only party that supports CCTV and it supports it strongly. There is just the faintest touch of overlap between the top (i.e. least supportive) end of the Labour error range and the bottom (i.e. most supportive) of the Tories'.
Trust and honesty. Liberals, Labour, and Conservatives all think politicians are honest. No doubt this is because the respondents are themselves politicians. Interestingly, the exceptions are the BNP and UKIP. Very interestingly, the BNP is united in cynicism, whereas the UKIP error range gaps-out dramatically on this question. The Greens' error range converges dramatically on exactly 46% agreement - they are almost perfectly in agreement that they don't agree.
Art and culture; only 'kippers, BNPers, and a very few extreme Tories don't support state funding of the arts.
Britain is a European country and is committed to the European Union. You can't argue with the data; the Tories and Greens average between 20-30% support for withdrawal, zero for the Liberals and Labour, and even the upper bound for the Tories is well under the 50% line. Obviously, the BNP and UKIP want out, which is obvious and after the election result, arguably trivial.
Pacifist fascists; bellicose conservatives; divided lefties and 'kippers. OK, so which parties are least keen on military action against Iran, even if they are caught red-handed building a nuke? The Greens are unsurprisingly 86% against with minimal error - perhaps the only occasion they would turn up a chance to oppose nuclear power! The other is the BNP - 82% against. Who knew we would find a scenario in which the BNP would turn up a chance to kill brown people? Labour, the Liberals, and UKIP would split down the middle - they overlap perfectly around the 50% mark. The Tories, however, are the war party - 39% against, with the lower bound well clear of the other parties. The UKIP result is strange - you'd expect them to be basically like Tories or like the BNP, but they are most like Labour on this issue, although they have a tail of happy warriors. The BNP is also the party most opposed to continuing British involvement in Afghanistan - even more than the Greens. Labour, the Liberals, the Tories, and UKIP overlap heavily around being narrowly in favour, although UKIP as usual gaps out when it's not discussing how much it hates the EU.
Even the Toriest Tories say they support UK Aid. This one's fairly clear - even the upper bound for the Tories is well below 50% and everyone else serious is much lower. UKIP and the BNP are strongly against, but their error bars are quite wide - clearly, they're not sure whether they hate foreigners enough that paying them not to be immigrants is a good idea.
Summary: We're a broadly social democratic European nation, with a few nutters for comic relief. And Chris Lightfoot's Political Survey results (the primary axis in British politics is liberty-vs-authority, strongly correlated with internationalism-vs-isolationism, and the secondary axis is egalitarianism-vs-libertarianism, but there is surprisingly little variance along it) from 2005 appear to be confirmed.
