What you hear in focus groups and conversations, people will give you 20 minutes of rage about how the borders are out of control. But then you start saying, practically, what are we going to do about it? What are we going to do about the 11 million here? What are we going to do to get some workers we need for the farms? Then people start having a normal conversation.

Parties that are majority parties are incoherent parties.

There is a virtue in shamelessness.

The brain is not the mind. It is probably impossible to look at a map of brain activity and predict or even understand the emotions, reactions, hopes and desires of the mind.

If you do have to look at polls, you should do it no more than once every few days, to get a general sense of the state of the race. I've seen the work on information overload, which makes people depressed, stressed and freezes their brains. I know that checking the polls constantly is a recipe for self-deception and anxiety.

Often, I go and see films where I can see the beats coming. So, if I read something where I don't see the beats coming and it takes me somewhere unexpected, that's a great thing to build upon.

I think actually in any party it's a sign of general health to have different views, and especially on the subject of trade.
