In pursuit of votes, David Cameron was in Inverness today, speaking in the chamber where the British Cabinet met in emergency session in 1921.
Perhaps it was that historical connection that led him to draw upon Winston Churchill for an attack upon the Alternative Vote.
Churchill - who attended that 1921 event as the Colonial Secretary - apparently called AV "the stupidest, the least scientific and the most unreal" method of electing politicians.
Mind you, Churchill wasn't always entirely consistent in his opinions.
A Tory who became a Liberal then a Tory again, he commented that anyone could rat on a party but it took a certain ingenuity to "re-rat."
On another historical note, those Inverness discussions forged the formula which led, ultimately, to the creation of the Irish Free State.
Mr Cameron did not seem in a mood to replicate such a process with regard to Scotland.
Addressing nationalists, he argued that Scottish independence would damage Scotland's economy, adding, with emphasis: "Don't these people get it?"
At roughly the same time, Alex Salmond was in Kilmarnock arguing that the latest round of economic figures proved the case for his government's efforts - and the need for more economic powers in Scotland.
Resolutely declining to "get it", Mr Salmond argued that the biggest threat to Scotland lay in the economic policies being pursued by the UK coalition.
Scotland needed fiscal autonomy.
Mr Cameron had more to say on the economy.
Labour's only offer, he said, was to spend much more money on interventionist schemes.
Deliberately echoing the departing Labour Chief Secretary, he said there was no money left: Labour had spent it.
Again unaccountably, Labour's Iain Gray declined to heed this message.
Labour, he argued, would be able to divert resources into tackling youth unemployment in particular.
Back in the Highland capital, the PM argued that the spending cuts were necessary to tackle the deficit and cut debt payments.
He argued further that Britain, including Scotland, would be revived through an entrepreneurial boost to the private sector.
Intriguingly, the PM's visit to Inverness coincided with a homecoming campaign tour by Danny Alexander, his Cabinet colleague as Chief Secretary to the Treasury.
Mr Alexander - once more, to widespread astonishment - disdained the advice on offer from the PM, at least with regard to Scotland. (As coalition colleagues, they share a wider perspective on the economy.)
The LibDems, he asserted, had the right ideas for Scotland with their proposals for regional development banks.
And AV was a good wheeze, whatever Churchill had said.
