Tonight there is another broadcasting set piece; an edition of BBC Question Time featuring the three main party leaders of the old parliament. Cameron, Clegg and Milliband. How they perform will be the subject of much analysis and polling, but how many votes will move from one to another is hard to tell.
What we do know is that Cameron looks a lot less secure than he did at the start of the campaign and Milliband and Clegg look stronger, especially Milliband. Aside from Nicola Sturgeon, the mega star, Ed is the big surprise to friend and foe alike in the way he and his ratings have grown as the campaign has unfolded. Lynton Crosby, the Tory guru hired from Australia is in part responsible through orchestrating a number of crass attacks on the Labour leader which backfired badly. But the Labour campaign has been better run, as has the much more limited Lib Dem effort, and Milliband has emerged as a measured and sympathetic leader with some kind of inner strength or conviction that people had not noticed before. This could be important, but as with everything in this unprecedented election, it remains impossible to say for sure.
