New ICM poll (specifying the party leader’s name):
Tory (Cameron): 42% (40% without mention of the leader’s name)
Labour (Brown): 29% (31%)
LibDem (Campbell): 17% (19%)
So Brown is 13 points behind Cameron; furthermore, his presence appears to worsen Labour’s performance (are they keeping from us the poll with Blair’s name instead of Brown’s?). How low does that number need to get before Labour starts reconsidering their options? 25%? 20%?
