Cameron takes ten-point lead

What is interesting about Labour's response to opinion polls is how each milestone isn't really a milestone at all. First Cameron drew level and it didn't matter. Then he took the lead. Of course he would, say Labour. Then he took a five point lead. Obviously! Now he's ten points in the lead, and what do Labour say? He should really be 15 points ahead ... I wonder what they'll say when he is?

The other interesting point is just how badly the weakened leadership of Sir Ming Campbell is doing. Poor LibDems, if they weren't so "wicked" and "shameless" locally I might feel sorry for them!
