Learning to tweet at 92 has been fun. But my musings should now be confined to elections, so I am signing off . . . until next year?

Rain can play a part - but it’s small. Lab voters go to polls later, so evening showers potentially hurt Lab more.

The polls have moved a great deal over the past two weeks. When people ask me for a prediction, I have to say I know that I don’t know.
