On the Today programme this morning, Menzies Campbell repeated a position which I find odd. In opposing a deal with the SNP, he said he was opposed not only to Scottish independence, but also to a referendum on independence.
But the case for a referendum is entirely separate from the case for independence. The case for a referendum - not just on independence - is that more direct democracy improves mental health, increases subjective well-being, helps promote civic virtue in the long-run, and - under the right conditions - helps come to a better decision.
It's perfectly coherent therefore to support a referendum on independence but oppose independence itself.
Indeed, a referendum could be a good way of stopping calls for independence; the result of the 1979 referendum on devolution was a big set back to the Nationalists' cause.
So, why is Campbell so hostile to the idea of a referendum. Of course, it might be that he doesn't trust the people - but if so, why does he call himself a Liberal Democrat?
