Contrary post of the day: the massive poll leads recorded in recent days make me nervous. It's good to have a lead, of course, and despite protests from various quarters, Cameron has in fact always had one apart from Brown's honeymoon bounce. When the history of this failing, tired government is written, I hope it will record the important fact that ICM's poll of a 6% lead for us in fifty marginal seats came before Brown's Yellow Saturday moment; caused it, indeed, and was not merely an effect of it.
But....
These shifts seem to me to be very fast. And Ben Brogan records that Lord Ashcroft is talking about a still impressive seven percent lead.
Labour, surely, is bound to recover from these lows. We all need to keep steady when strange polls are recorded (only a few weeks back one firm had Labour with a one point lead). I hope the hares will not start calling for the tortoises to get their skates on if these massive leads stabilise. You can almost hear it now: "Cameron couldn't sustain the momentum! Give me a real Conservative!"
My suggestion: forget the polls and campaign as if we were, say, three points behind; hard work in front but everything to fight for.
