This is the forty-first in a series of posts by Dr Robert Ford, Dr Will Jennings, Dr Mark Pickup and Prof Christopher Wlezien that report on the state of the parties in the UK as measured by opinion polls. By pooling together all the available polling evidence, the impact of the random variation that each individual survey inevitably produces can be reduced.
Most of the short term advances and setbacks in party polling fortunes are nothing more than random noise; the underlying trends – in which the authors 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 used to build these estimates of public opinion can be found here.
