Some politicians will tell you they never read opinion polls. I’m not one of them. I do read the opinion polls but I treat them with caution. The reason for caution is well demonstrated by today’s poll reported in The Independent newspaper. Their pollster reports that Liberal Democrat support has increased by no less than 50% [ yes Five Zero 50 per cent ! ] since their last poll five weeks ago. According to their poll, LD support has surged form 14% to 21%. Unlikely, err well very unlikely I think. Apparently the change is partly down to methodology. As I say polls should be treated with caution!
