The traditional tale goes that there is only one lake in all of Scotland, that of Lake of Menteith. The body of water was supposedly denied the more Scottish title ‘loch’ as a result of John Menteith’s betrayal of William Wallace, handing over the Scottish leader to be hung, drawn and quartered by the English.

It is a fine story, often repeated in pubs up and down Scotland, but there is infact several lakes in Scotland and ‘Lake of Menteith’ was only named so in the 19th century, long after William Wallace breathed his last desperate gasp of air.

The lesson remains that one should betray Scots at their peril and through this historic prism it is perhaps wise to view the plight of the Lib Dems, who look set to be hung, drawn and quartered at the upcoming Scottish Parliament elections.

Recent polling has had the Lib Dem voteshare at 12%, 11%, 10% and even in one instance 4%, figures that will significantly decrease the Lib Dem MSPs who decide to remain as candidates up to May 5th.

Clearly it will be a very difficult night for Tavish Scott, but it is the leadership ratings that are so eye-poppingly interesting. Prime Minister David Cameron has a leadership rating of -39%; for Nick Clegg that score is -58% with 75% of Scots disapproving of his performance and only 17% approving.

There’s a good reason why Clegg’s approval rating is significantly less that of the Prime Minister’s. As much as Scotland may not like it, we are getting what we expect from the Conservatives but have been let down, betrayed even, by the Liberal Democrats and Nick Clegg has been the face of that betrayal.

The risk for Scotland is that we end up with two political parties north of the border that are so toxic that no other party will do business with them, a situation that would leave coalition politics only possible between Labour, SNP, Greens and Independents. That’s a rather shallow pool to pull ideas from, particularly when the largest two parties can barely agree on anything at all.

A further potential result of prolonged low poll ratings for Nick Clegg is that the Scottish Liberal Democrats, for so long champions of a federal structure, will break further away from their UK counterparts. The ramifications for Scotland of such a move could be considerable. There have been several calls from within the Scottish Lib Dems for a referendum on independence and renewed calls with a renewed vigour from the party could be the quickest way to show that they are not Tory poodles, north of the border at least. Being seen to disobey Nick Clegg who is on -75% approval rating might not be the worst idea in the world either.

The pressing problem for the Lib Dems remains what their next big idea will be. All political parties have a right to exist in a proper democracy but the very essence of the Scottish Liberal Democrats deserves particular scrutiny given the lack of a natural shared objective. Even the bonding philosophy of ‘Only we Can Win Here’ is in danger given how many 3rd and 4th place spots the Lib Dems hold. What will the bar charts say we can only wonder.

What policies are being offered by Tavish’s party that are not readily available elsewhere? Free tuition? SNP and Labour have it covered. Environment? That’s the Greens’ domain. Health and education? There’s nothing that marks them out as special. That leaves a genuinely Local Income Tax which is surely an insufficient offering for a general election campaign.

In any election contest there is typically a main hero and a primary villain. For so long Tony Blair was the key electoral asset and whichever Tory leader was challenging Labour at the time the villain; at Holyrood last time around it was Salmond the hero and a jaded Labour party the villain; in last year’s election it was Clegg the hero and Westminster politics in general the villain. This time, a dramatic change of fortunes sees Clegg as the villain front-runner and a hero yet to step forward.

Scotland appears to be getting ready to send Clegg home to think again and, while we may not name a lake after him, don’t be surprised if you see Bog Clegg the next time that you venture into the Scottish wilderness.
