If some of the recent Westminster polling is reflected in next May’s general election, the SNP are heading for a landslide next May. Yet, at Ladbrokes, we still make Labour favourites to win most Scottish seats.

Despite the incredible rise in their membership, it’s not going to be easy keeping up the enthusiasm and momentum generated by the YES campaign. It’s also quite likely that they are experiencing something of a honeymoon effect from Sturgeon’s election as leader.

If they can persuade the huge numbers of previous non-voters who turned up to vote YES to support them next year, there is obviously a chance that they can pick up a very large number of seats. However, it’s not hard to imagine that most of those people will revert to type and not bother for the Westminster election. That may not matter, as it’s pretty clear that enthusiasm for Scottish Labour is at an all-time low. If Jim Murphy is elected as leader (he’s currently a hot 1-5 favourite) he might be able to improve that somewhat.

Currently, the SNP hold 6 of Scotland’s 59 seats. The Tories and Liberal Democrats combined should probably win around at least five seats, so to get a plurality ahead of Labour, the Nationalists are probably going to have to win about 27. Looking at Ladbrokes’ individual constituency odds, their 27th most likely win is Glasgow Central. Not easy.

Pretty amazing. Having come fourth with 11% in 2010, the SNP are now favourites to win the East Dunbartonshire seat next May and unseat the Lib Dem incumbent, Jo Swinson.

This could be one of the most interesting three way marginals in the whole of the UK, and we’ve seen support for all three main contenders. The shrewdies who took 50/1 about the SNP in the days before the referendum can be quite pleased with their position now.

Perhaps the SNP should be even shorter. If you take a look at electionforecast.co.uk their probabilities would produce odds of:

  • 4/9 SNP
  • 4/1 Labour
  • 10/1 Lib Dems

I would advise anyone to have a good look at the FAQs on their site before committing too much money on the basis of their forecasts. Predicting Scottish seats is incredibly tricky at the moment. The basic problem is how much can you anchor forecasts to the 2010 results, or do we just accept that the world of Scottish politics has totally changed and start from scratch? We’ll have a better idea once we get some constituency level polling in the New Year.
