The monthly ComRes poll for the Independent is out tonight. Topline figures are CON 34%(+4), LAB 37%(+1), LDEM 10%(nc), UKIP 12%(-2). The three point Labour lead is the lowest ComRes have shown since last September, and the 34% for the Conservatives the highest since last November.
The drop in the Labour lead and the fading of UKIP support is very much in line with the pattern we’ve seen in the daily YouGov polls, in ICM’s poll this month and in line with the sort of figures Populus are now showing… though it’s worth noting that MORI and some of the new online companies aren’t yet picking up the same pattern.
As to why the polls are narrowing, the harsh truth is that we really can’t tell. There is always a temptation that I see people falling into to reach for the issue you personally care about and ascribing changes in the polls to that (or “why the change in the polls shows that politicians should do the thing I like”) the reality is we can’t tell*, all we can do is look for rough correlations in timing. Personally my best guess is that’s its the result of the ongoing improvement in economic optimism we have seen over the past few months, a rather more controlled Conservative message and the decreased level of publicity UKIP have been receiving.
(*Whenever I make a point like this someone makes the suggestion of asking people. Oh were it so easy! Firstly, if you ask people who gave a different answer 3 or 4 months ago if they’ve changed their mind many won’t realise they have. If you ask why to those who have consciously changed their mind you get lots of don’t knows, general grumbles and some reasons that may be genuine causes, or may be post-hoc rationalisations for complex decisions we probably don’t even understand ourselves.)
