Lots of wishful thinking here.  IMO, May lost her lead because of bad non-Brexit policy initiatives - the dementia tax - a far too cautious approach - refusing to show up to debates, and a complete inability to present a face that voters could warm up to.  If this had been about Brexit, the lib dems and SNP would have done better.

In the end I think this will come down to a choice of the Norwegian solution - ie EU membership costs and rules with no seat at the table plus a big exit bill - and hard Brexit - ie WTO rules and full sovereignty.  If I were the Brits I would go for the latter.  And I think they will.  

Brussels is entering these talks like they hold all the cards but when the spectre of  the UK leaving and taking their money with them comes clear - that unity will fall apart very quickly.

And as for the idea of focusing on something else, get real.  Article 50 has been invoked.  The clock is ticking.  There can be no focusing elsewhere.
