Tomorrow’s referendum in Great Britain -- whether to remain in or exit from the European Union, the Brexit vote -- had its origins in a long-festering ideological schism within the ruling conservative party. Sound familiar? That smoldering spark has become a raging political inferno, fanned by Boris Johnson’s populist Britain-first rhetoric and an anti-establishment sentiment among voters. Hmm, that sounds totally familiar. Europe hasn’t helped its own cause with its dithering response on debt and immigration. Now it’s another do-or-die moment. The current betting is that Britain will remain in the European Union. The surer bet is that nothing will be settled.
