Scotland will soon be suffering from a monumental hangover. There will be a lot of hurt heads, a lot of tears and, without a doubt, an immense amount of anger that will last who knows how long — weeks, months, maybe even years — if Alex Salmond's dream of independence comes true.

The Sept. 18 referendum on independence is quite unlike any other United Kingdom election I have witnessed. It is much more visceral, with so many complicated currents swirling beneath one simple question: Is Scotland in Britain or out of it? There are a lot of people going with their gut instinct, and you sense that if the outcome goes against them, the simmering rage will finally bubble over.

Rioting in the streets? Perhaps.
