PoliticsHome has today published its YouGov survey of some 240 marginal seats, with a sample of around 35,000 voters, providing the most complete picture of regional polling trends, and likely constituency results. The results are fascinating – but, as with any polls, it comes with health warnings.
The most important is that, even with the large sample size, the number of people in each individual seat is not high enough to give reliable voting intention figures for individual constituencies. This is an especially relevant consideration when looking at Lib Dem MPs and target seats, as the ability of a local party to organise an effective ‘ground-war’ campaign often marks the difference between a successful hold / gain and a near-miss.
For example, the PoliticsHome survey predicts that Chris Huhne’s seat of Eastleigh will be a Tory gain based on the Lib Dem – Tory swing in the south and south-west. However, I will eat my hat (really, I will) if Chris is unseated.
