Today’s ICM phone and online polls are a reminder that the polls aren’t going to offer much certainty about the result of the EU referendum. ICM’s traditional phone poll has IN ahead 47 to 39, and with the don’t knows excluded up 55% to 45%. This would suggest that IN is on course for a fairly comfortable victory. But its online poll has Out up 47 to 43, and with the don’t knows excluded ahead 52% to 48%.
Phone polls are generally regarded as slightly superior to online ones, they are certainly more expensive. So, I suspect that most people in Westminster will take these polls as a sign that IN is probably ahead.
Interestingly, Number 10 briefed out some of its own thinking on the current polls to the Sunday papers. A ‘polling expert with links to Number 10’ argued that while the headline numbers suggested a tight race, the underlying numbers—as with the general election—point to a quite different result: a comfortable victory for IN.
Oddly enough, though, I suspect that for so-called Project Fear to really bite, it will need Out to be ahead. In Scotland, the warnings of the danger of independence seemed to have more traction after that You Gov poll showing independence ahead than they had before.
