"A close result would allow the Scots to wrestle more power from Westminster presumably and not let the matter rest?"

The defeat, by whatever margin, will be the end of Salmond.

I seem to recall that in the past the SNP have said they will abide by the result for a generation.

However, with 16 year olds getting the franchise this might be shorter than the usual!

"An overwhelming rejection would put the matter to bed and no further concessions from Westminster?"

The matter will never be "put to bed". It is now there, and will stay there, niggling away for ever.

I would not be surprised to see some sort of move towards federalism, rather than union, in the next hundred years or so.

I hope you're right, but I fear it is a forlorn hope.

Unlike most elections, there are very few "undecideds" to be swung, views already being very polarised, and likely to become more so.

This is not about politics in the normal sense, where any result is reversed in time.

A "Yes" vote is for all time.

You should also not discount incomers and other immigrants of whom there are very many, most of them, unlike me, not voting in favour.

(This leads to a peculiar situation at home, where my wife, who is a Scot, is against!)
