Poll Trouble

Ken Livingstone's campaign has thrown something of a political fit over YouGov polls suggesting that Boris Johnson is way ahead. They have released a press statement calling into question the methodology of these polls and declaring that:

Ken Livingstone's campaign therefore states clearly that it does not accept this poll as accurate and, in light of its continuing errors, it does not regard YouGov polling on London as accurate.

One is inclined to tell them to chill. Only one poll really counts, the one on May 1st. But if the Livingstone campaign is so threatened by a YouGov poll that they feel the need to attack its results and methods, well, what does that tell you about confidence levels at Labour HQ?
