One thing the Tory high command should take away from the ICM poll, is that Labour is—remarkably—ahead on the question of who is most trusted to set taxes. Now, we know from polling that taxes on the rich are, at least initially popular. But this number implies that the Tories need to do a lot more to emphasise how many other taxes Brown has raised and ram home the fact that the gap in Labour's plans mean that they will have to push through considerable tax increases if they win.
The poll also suggests that more than half the electorate will watch one of the TV debates. Even if this number is inflated by people wanting to sound like good citizens, it does indicate that the audiences for these debates will be huge.
