Much has been made of the intimidation and unpleasantness that has crept into the closing stages of the Scottish referendum campaign.
My colleague, Tom Bradby, says he experienced less personal hostility working in Ulster in the 1990s than in recent weeks in Scotland.
And there is no question there has been a nasty side to campaigning here.
For what it’s worth, it seems the vitriol has been more prevalent following the ill-tempered confrontation between Alistair Darling and Alex Salmond in the second televised debate.
The seismic nature of the first poll putting the Yes camp ahead also seemed to mark a rapid rise in the temperature of the campaigning.
And Tom is right. Particularly unedifying has been the crass and unsubtle attempts to intimidate journalists simply doing their job.
But and here’s the point, there is a bigger, much more optimistic picture here on the eve of one of the biggest days in modern British history.
In Edinburgh this afternoon, I walked through a city completely energised by politics.
On the streets, in the pubs and restaurants the talk is only of the referendum.
There is nervousness, anxiety, excitement, apprehension and expectation…all fuelled by an atmosphere unlike anything seen before in recent UK politics.
Suddenly politics matters, people care. And those previously dismissive and disillusioned are embracing the arguments, devouring the information produced by both sides and are preparing to have their say.
A few days ago, rather foolishly, Alex Salmond likened events here to the first democratic elections in South Africa in 1994.
He was rightly derided for such a comparison. Mr Salmond, for all his qualities, is no Mandela and in South Africa 25 million oppressed and brutalised people were voting for the first time to end the evil of apartheid.
I was there that day 20 years ago and a more emotional day of voting I have never witnessed.
They knew, as they queued, that they were voting to change their country and their lives forever.
The result, of course, was never in doubt, but still that vote was the most important political act they would ever carry out.
So in that sense, and only in that sense, there is a similarity.
Tomorrow millions of Scots will never cast a more important vote.
It will determine their future, it will shape their life and that of future generations here. It is that important.
Scotland knows it and is electrified by it. If you don’t believe me, just take a stroll through Edinburgh.
