The last Cornish constituency poll of the election appeared yesterday. This was for North Cornwall, now polled four times in a year by Ashcroft. Over that time, the share of the vote for Lib Dem Rogerson and Tory Mann has risen, while that for Ukip and Labour fell. The Greens have hovered around the 5% mark.
Although there’s been a considerable shift back to the two familiar parties since last year, this poll shows very little change since the last one taken in March. Rogerson continues to eke out a narrow 2% lead, but one still uncomfortably within the margin of error. It looks like the winner here will be he who squeezes the other parties most in the last five days. Mann has a 14% Ukip share to aim at, while Rogerson can try to steal back a 13% Labour/Green/MK share. Neither has an obvious advantage in the tactical vote struggle, therefore.
Moreover, the total score for others, at around 27%, has not shifted over the last month of campaigning. It could be that the low hanging fruit was picked over the winter. The Ukip and Green vote now looks fairly stable. Moreover, the leap in the score for others over the last month by 2%, from 1% to 3%, may prove welcome news for MK. Here’s the change since the last election.
