Bullshit. Every election in the history of ever releases a poll that says "oooh its neck and neck now".
I'm starting to suspect that they can't or won't release polls that say "60% in favour of x, 30% don't care, 10% against" because of the backlash they'll get from both camps.
Eg "Your poll means our supporters won't turn out now because they think they've already won" Or, "your poll is a lie because you only asked x,y,z people".
