"Ignore 'voodoo polls' from newspaper websites – they reflect the party allegiances of that website’s audience (the Guardian’s web poll has Brown second – shock! Daily Mail has Cameron first- wow!), do not attempt to be politically balanced or representative and are easy for interested parties to manipulate."

"The questions now are who people think is the winner once it has been filtered through the media tommorrow (i.e. today), and more importantly, what impact that has on voting intentions, how much of a boost will the Lib Dems get? Our first chance of getting a really good idea of that will probably be the polls on Saturday or Sunday."
