This is the forty-fifth in a series of posts that report on the state of the parties as measured by opinion polls. By pooling together all the available polling evidence we can reduce the impact of the random variation each individual survey inevitably produces. Most of the short term advances and setbacks in party polling fortunes are nothing more than random noise; the underlying trends – in which we are interested and which best assess the parties’ standings – are relatively stable and little influenced by day-to-day events. If there can ever be a definitive assessment of the parties’ standings, this is it. Further details of the method we use to build our estimates of public opinion can be found here.
As we approach the electoral business-end of this parliament, the party machines are gearing up for the campaign proper – with a lot of nervous watching of the polls for signs of a sea change in opinion. Are the public steady in their voting intentions, or are they starting to move as polling day nears? Our latest report tracks the polls up to March 1st, so just before the eruption of ‘debate-gate’ arguments about the Prime Minister’s reluctance to appear in televised debates, and before the most recent run of polls that look potentially more favourable for the Conservatives, though as ever we reserve judgement until the underlying trend is clear.
Our evidence suggests that the parties remain neck-and-neck, with Labour support at 32.2% the same as last month, and the same as our estimate at the start of December too. The most recent erosion in Labour’s lead, which has now all but disappeared, has not been due to a decline in Labour support, as was true for most of last year, but instead due to a slight improvement in Conservative fortunes. The Tories have gained 0.3 points this month, rising to 31.5%, one of their best performances in the past year or two. However, despite recent gains, we still have them in the 30 to 32% rut that they have been in since the infamous “omnishambles” budget in 2012. If the more recent uptick in support seen in March’s polling to date is sustained, the Conservatives might break out of the rut just as the election finish line approaches. This remains to be seen.
UKIP have fallen back again, down 0.7 points to 14.8%, their lowest share since September. While not quite at the peak they achieved in the autumn, possibly due to reduced attention over the past month, Farage’s radical right outsiders have become part of the political landscape and continue to attract enough support to threaten to wreak havoc in May. The Liberal Democrats have made a slight gain, rising 0.4 points to 8.4%, but still look destined for severe electoral pain. One much-caveated forecast based on data from the British Election Study suggesting they could win just one seat. Their fate in Parliament continues to hang on the ability of their MPs to generate ‘personal votes’ sufficient to swim against the tide of national unpopularity.
Finally, the Green surge appears to have levelled off for now. We have the party up just 0.1 point past this month, to 6.4%. This is a new record, and puts support for the party just below the Lib Dems, but the questions remain how ‘soft’ much of the Green vote is as Election Day approaches, and how effective the Greens will be in channelling rising national popularity into successful local campaigns.
Based on these current estimates of support for the parties, our vote forecast points towards a result in May that is too close to call. We put both Labour and the Tories on 33.7% but with a wide range of uncertainty. Our forecast indicates that Labour support could fall within the 30.1% to 37.2% range and Conservative support in a slightly narrower range — between 31.9% and 34.4%. In short, history suggests there is still time for either Labour or the Conservatives to pull ahead, though neither has a clear advantage right now. The Liberal Democrat forecast continues to edge downwards as the long hoped for recovery in support continues to elude them. It now stands at 8.8%, which would be just over a third of the vote that they won in May 2010.
As the four party politics of 2014 has given rise to five or six party politics, and as UKIP and the SNP appear to have become part of the electoral landscape that has proved resilient, the Polling Observatory team has produced its first set of forecasts at the constituency level. On Friday, 13 March, 2015, we will release these seat level forecasts, along with an explanation of how our model of constituency simulations works, and estimates of each party’s chances in every seat.
