Alternative Voting campaigns in the UK

On May 5, UK citizens will head to the polls in a special referendum to decide if the country should move to an Alternative Voting (AV) system.  Unfortunately, recent polling predicts the measure will fail as the “no” campaign seems to be building a bigger lead.  There are plenty of places to read about the politics of the referendum, so I just wanted to focus on the campaign tactics being used by the respective camps and briefly speculate if there is any evidence they are having an impact on vote preference .   First, there is this widely clever ad from the “Yes” campaign.

This is a great advertisement, but it’s actually not the main talking point of the “Yes” campaign, which seems to be pushing the notion that AV will make Representatives work harder.

Your next MP would have to aim to get more than 50% of the vote to be sure of winning. At present they can be handed power with just one vote in three. They’ll need to work harder to get – and keep – your support.

This doesn’t sound like the most convincing argument to me, although I’m sure it was the message that tested the best in focus groups.   Still, I find it much better than this “No” campaign spot, which seems to better represent that campaign’s overall message.

In order to understand how an AV system works you need to be able to count to three;  it’s really not much harder than that.  This isn’t, however, a surprising line of attack; efforts at voting reform in the United States have often run up against the same.  As misleading as that ad was, I think the false trade-off between critical national interests and voting is even more absurd.

Keeping a FPTP system will help the UK fund its military in the same way cutting NPR will help the United States eliminate the national debt.  This ad is even more insulting than the last.

Are any of these campaigns effective?  I think the evidence from surveys show that it’s difficult to prove:

The poll shows that while Liberal Democrat voters are overwhelmingly in favour of reform (66 per cent to 26 per cent) and Conservative voters are overwhelmingly opposed (76 per cent to 19 per cent), Labour voters remain divided, with 47 per cent backing FPTP No and 41 per cent backing AV.

To me, this implies that vote choice might be predominantly a function of partisan preference; the Michigan Model  for the United Kingdom.  Of course I don’t really know enough about UK politics to know if partisan attachment is more or less stable than the United States.  I would think the nature of their parties would make it more so, which would lead me to expect a greater correlation between party ID and preference on AV. Still the fact that support for the referendum has swung so drastically, with a large number of undecideds moving to one camp, may be evidence that people who have not paid much attention are now taking cues from party elites.  Not the best way to choose an electoral system, but another example that they are highly endogenous to their political environment.
