Everyone’s probably familiar with the concept of tactical
voting. Under the First Past the Post system, supporters of parties which are
smaller in the constituency often vote for one of the more major candidates.
For instance, some greens will lend their vote to Plaid Cymru and so on.
The electoral system for the Welsh Assembly, with two votes –
one for the constituency and one for the region – provides a chance to
understand which groups vote tactically, and for whom.
Here’s the statistics then. It’s clear that some of the
parties get less or more votes on the regional vote than on the constituency
vote. The Greens got about 50% extra votes in the region than in the
constituency, following their campaign to get a Member for the region. The
libdems got a lot fewer votes in the region than in the constituency. Labour was one of the other
parties who got a lot more support in the region than in the constituency.
In order to understand where the votes are going between the
main parties, the figures for the regional vote need modifying. 757 people
voted in Ceredigion but not in the regional vote. Also, a small number of votes
went to parties who didn’t compete in the constituency. After ignoring these,
and raising the number of regional votes for the main parties so that the
number of electors is treated as equal in the 2 competitions, we see the
following differences, between the regional votes and the constituency votes in
Ceredigion:

This suggests several things. The most obvious is that the
libdems lost over a third of their support on the regional list, and given how
many people had voted for the LibDems,
this meant over 3000 votes.
Another clear finding is that lots of Labour, Tory and Green
supporters voted tactically in the constituency. The three parties each added
around 50% extra to their vote at the regional list.
One of the very interesting things is how stable Plaid Cymru’s
vote was. This is surprising to an extent, since Elin is very popular in the
area, and many people on the doorstep were very supportive of her. But it looks
like the local candidate is a “shop-font” for her party in general – Plaid Cymru
supporters vote for Elin in the constituency and then vote for her party in the
Region.
I won’t deny that Elizabeth Evans of the libdems also has a
lot of supporters in Ceredigion. But if they support her, the libdem vote would
be expected to be stable on the regional list also.
The only possible conclusion is that the libdem vote in
Ceredigion is a coalition vote – a tactical vote against Plaid Cymru. Many
Conservative and Labour supporters, and some UKIP supporters also, vote for the
libdems in an attempt to stop Plaid Cymru from winning the seat. Alun Williams
wrote about this phenomenon some time ago: http://bronglais.blogspot.co.uk/2010/05/ceredigion-8000-why.html
This also reflects the very negative campaign that the
LibDems have run in Ceredigion this year, where several LibDem leaflets
appeared to focus more on opposition to Plaid Cymru than on promoting their own
party. Clearly the bar charts which show that the election is a two-horse race
have had an effect.
Very fortunately, Plaid Cymru ran a very postive campaing in
Ceredigion this year, and the result is clear. Elin Jones has increased her
majority, and the attempt to build a coalition against Plaid Cymru has been a
failure. Imagine for a moment: how different would Ceredigion politics be if
everyone voted for their favourite political party?
