There is evidence that the media is deliberately "adjusting" polls as they feel the truth is too outré
And as posted upthread the Tories have only just worked out that their paranoia about Reform, and natural antagonism to Labour has meant they and their client media have pretty much forgotten there was a LibDem party. (Why do you think Ed Davey was doing all those stunts ? It was the only way to get the LibDems in the news most days.)
If the main prize Friday is a Labour win, gilding the lily would be the LibDems exacting revenge on the Tories for 2015 and silently becoming official opposition. If that happens, then childish as it may be, I want Ed Davey to go past CCHQ on the back of a motorbike flipping the bird to them.
