“Do you think the Labour government of 1997-2010 or the current Conservative-Liberal Democrat coalition government has been more effective in dealing with each of the following areas”?

This from YouGov’s poll for the Times RedBox would suggest that on every important issue the voters rate this government higher than the last Labour government. The personal leader ratings of Cameron are high and Miliband’s are tragic, so why is Labour polling a 7% voting intentions lead? Answers to Lynton Crosby on a postcard please… (Clue: it is purple.)
