From what I heard, the tories are basically ignoring the EU election campaign. There is too little at stake, and too many of their loyal voters are just voting Brexit to send a message to London/Brussels. Ignoring the election allows them to save face when the eventual loss occurs, and in their minds, their voters will just return when the country eventually leaves.
I wonder if they almost want to be crushed by the Brexit party so that they can push harder for Brexit.
There was certainly some tories on the BBC locals stream that I watched making the argument that their couple hundred losses (at the time) were necessary sacrifices to tell May and the frontbench to get on with it.
It's hard to believe that anyone among the Tories would really think that it would be a good strategy. Too fakking risky.
It feels more like damage control by putting on a brave face. "Well, we don't care/send a message" or whatever.
