Angus Reid has released details of a UK-wide poll that contains any number of headlines that can be drawn from it, including:

SNP now UK’s fourth party
Labour holds slight poll edge
Lib Dems slump to 7% in Scotland
SNP and Labour neck-and-neck in Scotland

I, of course, have gone for a different tack, choosing to focus on the result that 60% of Scots disapprove of David Cameron’s performance as Prime Minister but a higher still 63% of Scots disapprove of Nick Clegg’s performance as Deputy Prime Minister.

With the standard caveats of sub-sample polling, it is difficult to tell if such a result is intuitive or counter-intuitive really. The Lib Dems shoring up a Conservative Government was always going to be a tough sell in Scotland so it is perhaps expected that they come in for the strongest disapproval. However, Nick Clegg’s defence is that his party has taken the right-wing edge off what a Conservative Government would have otherwise done with some left-wing coalition victories, an argument that is often overlooked and one that I personally have a lot of time for.

However, the numbers do not lie and it seems it will be Nick Clegg’s turn to follow in the footsteps of electorally toxic individuals such as Tony Blair and Barack Obama when May ’11 comes around.

It is of course an issue of trust that is undermining the Lib Dems at the moment. The sight of ‘VAT bombshell’ posters and signed tuition fee pledges moved their poll figures onto the quicksand after the broken promises and it is not clear what may bring them back onto firmer ground. It is also not difficult to imagine Nick Clegg arguing his case north of the border and being booed and jeered throughout, exacerbating the problem rather than solving it.

The Scottish Liberal Democrats are of course a separate entity which may help insulate them from the worst effects of London-based decisions but with little to mark Tavish Scott and his team out as ‘different’ (the student vote is surely now long gone) then of course they will be tarred with the same brush.

With the two-horse race looking certain to be a continuing narrative right up to May 2011, particularly with the SNP closing the gap on Labour, perhaps the best that the other parties can hope for is anything other than a drubbing.

If so, Deputy Prime Minister and his Scottish colleagues have a lot of work to do.
