A BREXIT PREFERENCE CASCADE? Boris Johnson exclusive: There is only one way to get the change we want – vote to leave the EU.

James Bennett emails: “Are we seeing a preference cascade for Brexit? Although many are already for it, of course, mostly they have been either old-line Tories or working-class marginal malcontents. Boris and Zac are part of the rich, well-connected, cosmopolitan London set which has always been presumed to be Europhiles. Watch this phenomenon.”

I think that when the EU ship set sail, it offered dazzling opportunities for graft and self-aggrandizement, free from tedious popular scrutiny and control. But now that it’s taking on water, the smarter members of the political class are scouting out the lifeboats.
