Lord Ashcroft has released a second tranche of polls in Con-v-Lab ultramarginals, full details are here. It’s a repeat of his first polling of Con-Lab seats in April and now as then, Ashcroft polled the 12 most marginal Conservative held seats with Labour in second place, plus two other seats (South Thanet and Great Yarmouth) that he thought might have interesting UKIP results. Note that this wasn’t what we’ve often called a “marginal poll” in the past (a single poll of a group of marginal seats), it was 14 separate polls, one in each seat, individually sampled and weighted.

In April, the average swing in the 12 Con-Lab ultra marginals was 5.5% from Con to Lab, the same as in the national polls at the time. In other words, Con-Lab ultra-marginals were behaving right in line with national polling.

The average picture in the national polls is unchanged since April – the national swing from Con to Lab in GB polls conducted during the time Ashcroft did his latest fieldwork was 5.4% from Con to Lab. Lord Ashcroft’s findings in the marginal polls however have shown a slight weakening in the Labour position relative to the Conservatives, looking at just the 12 ultra-marginal seats the Conservatives are down by about 1.5% on average, Labour down by about 2.7%, UKIP up by about 4.5%. This looks like a European boost – the previous poll was done before the European election campaign, this one started in mid-June. The average swing in the ultra-marginals is now 4.9 from Con to Lab, meaning an increase in UKIP support has slightly hurt Labour. While the difference is too small to really make a fuss about, it also means that Ashcroft’s polls now show a slightly smaller swing in Con held marginals than nationally – in line with what we’d expect given the normal incumbency effect.

In two of the seats polled, Thanet South and Thurrock, UKIP were ahead in voting intentions, which will be enormous help for them in convincing voters they are a viable general election vote in the local area.

  1. Seeing the news, I start to wonder: has there been any polling on attitudes to Israel/Palestine? – I have a feeling that attitudes will have shifted over the last 30-40 years, but don’t know if I’m right on that.

    One can indulge in stereotypes, so I won’t rise to the bait. Just close your eyes and see a front door with a ‘save the whales’ sticker on it. A likely Conservative supporter do you think?

    Another one, front gate ‘no hawkers’ on it.

    Damn, I rose to the bait.

    Canvassing is fun and good exercise. In May to August, do wear a hat between calls, especially if you are as follically challenged as I.

  5. @Peter Crawfors: “I can’t believe it, because it’s very naive to believe one academic study which says that a 5 week campaign doesn’t work,”

    Who does, though? What I said was “if the campaign is as ineffective at changing minds as some research has suggested”. And some research has suggested that.

    “It’s a ‘system’ in 2 ways…”

    There are variations within England too, e.g. in London transport is largely devolved but elsewhere generally not. England has no unifying political body.

  7. Has anyone conducted a poll of what people who voted LD in 2010 expected to be the outcome? The suspicion (not objectively tested) is that Lab-LD switchers anticipated a minority Labour government and are highly unlikely to vote in similar swathes again. Current polling comment does not seem to reflect this scenario.
