The fledgling “yes” campaign for AV says it is too early to make premature judgments. The Electoral Reform Society, for example, says that polls will inevitably jump around given that the formal campaigns have not yet started. The referendum is not until May – and could even be in September if rebel Tory MPs and Labour MPs unite to amend the relevant bill.
But our analysis for today’s FT shows that the yes campaign was ahead by 28 points in May (according to ComRes) and as little as 1 point ahead in recent weeks (says YouGov). It may not be a co-incidence that support has dwindled just as backing for the Lib Dems (the main proponents of electoral reform) has also fallen sharply.
