With a fresh Budget to assess, every polling house was in the field searching for a Budget bounce. And you would never read about it, but they found one. The combined message is one of a small bounce-let for the Government. (And this is where I feel a compelling need to utter the following mantra as a public service: don't confuse correlation with causation. Just because some polls went up, it still could be noise, and even if its real it doesn't mean the Budget made it happen).
