And just because the postal votes have gone, you think you don't need to bother about those constituents?
Did you not see this bit:
at this stage I am only interested in identified supporters who will vote in person
Quite clearly, if the focus of the day is persuding people to vote for you, what's the point of working on people who've already voted? I doubt any councillor or politician at any level is going to be thinking about long-term policies on election day. They can get back to that afterwards.
It seems the local council round here do care, and do make an effort, so I'm keen to use my vote.
Also, 1 vote for anyone who isn't UKIP is a good thing.
