Did The Lib Dems Cost Labour The Election?

There have been howls of protest from Labour voters at the prospect of a Lib/Con coalition. The main complaint is that anyone daft enough to vote for Clegg has caused a Tory government. But is it true?

Using data from The Guardian, we can see if the Lib Dems cost Labour a majority.

In how many seats did a Labour candidate lose to a Conservative? 137.

But this doesn't tell the whole story. In Clacton, even if all the 5,577 Lib Dem votes had gone to Labour, the 16,376 is still well short of the Conservative's 22,867.

So, in how many of those seats, would the Labour candidate have won if every single Lib Dem voted Labour? 92.

Conclusion

If every Lib Dem voter in a Lab/Con marginal had voted Labour, the result would be Con = 214 Lab = 350 Lib = 57

So, the Labour Party would have ~3% majority in Parliament. Only 24 seats. A majority, sure, but not a hugely useful one.

Remember, that's assuming every single Lib Dem voter in a Lab/Con constituency voted Labour.

Would you call that the Lib Dems costing Labour the election?

The Stats

This table show every Conservative won seat where Labour came 2nd. What would have happened if 100%, 75%, or 50% of the Lib Dem vote went to Labour. As some have mentioned in the comments, there is no guarantee that Lib Dem voters would automatically vote Labour. Given that support for the Lib Dems only went up 1% nationally, it's hard to credit Labour's defeat to the Lib Dems.

Even if Lib Dem voters cost Labour the election... I don't care. We are now without a party who destroyed civil liberties, gave us SOCPA and all the other awful anti-terrorism legislation, drove us into two illegal wars, removed the commitment to socialism from their own manifesto, cut services to the homeless, introduced ID cards and the database state... I could go on but my dinner's ready and I really don't give enough of a toss about Labour to bore you with any more of their shit...

A better source of data would be to base it on Lib Dems' actually known second preferences - not all Lib Dems are left leaning and many would resort to the Conservatives if there were no Lib Dem preference.

From this Channel 4 News article based on a poll by comRes: http://www.channel4.com/news/articles/vote_2010/poll+of+polls+election+race+tightens/3627192 Lib Dem voters' second preferences nationwide were: 34% Labour and 26% Conservative. It would be interesting to see what figures your calculations are based on the (obviously error-prone) assumption these proportions would be applied in each constituency.

(As would the figures for what Labour & Conservative voters' second preferences would be as well in constituencies that their candidates had lost)

Labour is naive if it thinks that its the next choice for every Lib Dem supporter. I could never vote for such an authoritarian party. And one could also argue, that Labour has costed the elections for Liberal for decades, after all the Liberal Party was there first.

One thing that I find amazing is how british people loose their time discussing if this party cost another the election or not instead of talking about the intrissencal anti-democratic electoral system based on the uninominal process where a lot of votes are set to /dev/null. How is it even possible to consider democratic a system where one can get 35% of the votes and the majority of the seats in parliament? How come you can even consider this democratic??
