Q. Why is there so little public sympathy for farmers? A. Because at election time the fields are festooned with Tory boards and placards. Only in Wheatley was there any sign of Lib-Dem boards and one solitary Labour one.
Not quite sure really why people put up the boards, really. No-one is going to think 'well, that farmer / neighbour in sodding big house is going to vote Tory, the scales have fallen from my eyes and I will likewise'. I suppose in the pre-interweb days it was a clue as to how to tactically vote, but we have the interwebs for that now. Not that the answer in that particular constituency is going to be a difficult one.
