Believe it or not, after the parties have expended so much effort in this campaign, so many photo opportunities (did you like the PM better in the one with the avocado or the glass of whisky?) and in the case of Ed Davey, so much dignity, there are still lots of people who do not know which way to vote.
At least one in eight are still considering who to opt for, according to one estimate. That includes about two million who voted Tory last time and are now tossing coins to decide which way they go now.
