I've been doing a stint of knocking up postal votes and very rewarding it has been. The conventional wisdom is that people who bother to register to get PVs are going to vote. It is true the turn out is much higher than non PVs but as more and more folk register the turn out will slip. Anyway there is always someone who rings up after the polls have closed to say that they have forgotten to send their vote back.
I have found a great deal of enthusiasm for voting with people freely telling me that they have supported us-and that included people who we had previously canvassed as 'soft con'. That pattern was repeated again this evening when I was out in Ainsdale and got a really warm reception.
