ComRes released their latest poll of marginal seats today. As regular readers will recall, ComRes’s marginal polls cover the 40 most marginal Con-v-Lab seats (25 Conservative held, 15 Labour held). Unlike Lord Ashcroft’s marginal polls (which are actually a series of individual constituency polls in seats that are marginals, which we can aggregate together to get an extremely large sample across a group of marginal seats) ComRes’s poll is a more traditional marginals poll – a single poll of a group of marginal seats, meaning it gives us a measure of those seats as a whole, but has far too few people to tell us anything about the individual seats within that group.
Latest voting intention figures in these marginals with changes from the last time ComRes polled them in September is CON 31%(+1), LAB 39%(-2), LDEM 7%(+1), UKIP 18%(+1). These seats had Labour and Conservative equal at the last election so an eight point lead here is the equivalent of a four point national swing and a one point Labour lead in national polls…pretty much exactly what the national polls have been showing lately (actually if you look at the crossbreaks of the poll they suggest a swing towards the Conservatives in the Conservative held seats, a swing towards Labour in the Labour held seats, but given the sample size of those two groups and that the poll is only weighted at the level of all forty seats I wouldn’t put too much weight on that).
Note also that, judging from the tables, ComRes have switched over to prompting for UKIP in their main voting intention question in this poll – as with their last national poll, it does not seem to have had a major effect (UPDATE – I think this is because ComRes have changed turnout weightings, so that there is a tighter turnout filter for the Greens and UKIP than for the main parties). Tabs are here.
There should be another batch of Lord Ashcroft polls of individual marginal seats later this week.
