It seems I can kill two birds with one constituency. Yes, Orkney & Shetlands has been held by the Liberals since 1950 which is a UK record.
But why? What is it about those two islands that endears them to the Lib Dems and, more specifically, Jo Grimond (1950-83), Jim Wallace (1983-2001) and Alastair Carmichael (2001 to, well, however long he wants I reckon)? Indeed, per the Rough Guide to Scotland, "Shetland, in nearly all respects, a complete contrast with Orkney". In the world of Politics, that doesn't seem to be the case.
The funny thing is, Alastair Carmichael wasn't even born on either island, he didn't grow up there, study there, work there or, as far as I understand it, even live there before being elected as the local MP eight years ago.
Not that any of that really matters of course, but I do find it all adds to the intrigue of these rather magical islands.
Maybe it's merely the farmer link, Lib Dems do seem to generally do better in rural parts of the country, but it seems in the 2010 General Election and no doubt beyond, there will only ever be 58 constituencies truly up for grabs.
(While writing this post I was tickled to learn that Shetland has its own Wikipedia. It's called, I kid you not, Shetlopedia. Love it.)
