They haven't got a clue.
My theory is that there's always been a duplicity to Tory campaigning. They say one thing but mean another. The problem is, that they know believe the nonsense they spout. We are through the looking glass.
For the record, have a look at constituency polling coming out. It's backing up what I said a few weeks back. Their polling in marginals doesn't match national voting intentions. The Lib Dems in the South are within touching distance of seats such as Wokingham and Esher, while Labour are holding Gedling comfortably at present.
Simplistically if Labour are lower in the South and up in the north, and the Lib Dems vice versa they're in big trouble.
Overall, this really isn't good news for Labour.
They need to shift the focus from Brexit... somehow.
