If you were to believe a lot of the campaign leaflets out there, particularly those that take you down the yellow brick road of bar charts on Lib Dem literature, it is just as important to be in second place when challenging for a seat than it is to have a decent set of policies to take to the voters.

It is not out of the question for people to vote for party X because they want party Y to form the next Government because they don’t want party Z in there. In these cynical times, tactical voting has never been so rampant.

So, with that in mind, I thought I’d do a bit of an analysis of who is where in the 73 FPTP constituencies of Scotland going into this General Election, seeing as how important it seems to be.

Taking a high level view of the lay of the land by calculating the weighted average of positions across each of the constituencies from the 2007 election, this gives you a feel for where each of the parties stand at the current time.

SNP is 1.85th
Labour is 1.93th
Tories are 3.09th
Lib Dems are 3.09th

(Note that this compares with the 2005 GE as follows:
Labour are 1.47th
Lib Dems are 2.53rd
SNP is 2.78th
Tories are 3.19th)

Most ardent fans of politics and elections can rhyme off the number of FPTP MSPs each party has but I’ll do it anyway. The Tories have 6, the SNP 21, the Lib Dems 11 and Labour 35, which is 6+21+11+35=73.

However, what about 2nd place? Which party is waiting in the wings more than the rest?

Well, as some may have already worked out from the SNP’s prime ‘1.85th place’, Labour are 2nd with 18 2nd placed spots, the SNP 1st with a whopping 43 2nd placed spots, the Tories have 7 and the Lib Dems 5 (4 of which are 2nd places to the SNP).

This, for me, is the reason why the SNP has such a great chance to record a stunning victory in this coming election. They are in 1st place in 21 seats and 2nd place in 43 seats. Do the seat projections for the current crop of polls take into account the tactical voting that will take place? The consideration that always takes place whereby many voters only decide between who is 1st and 2nd from last time around? If not, the SNP’s result may infact be higher than the already remarkable results that have been predicted since they are 1st or 2nd in 64 of the constituencies, a full 88% of all constituencies. The equivalent figures for Labour, Lib Dems and Conservatives are 73%, 22% and 18% respectively.

With a dramatically declining voteshare and only a handful of second place spots dotted around, it is difficult to find a constituency where the Lib Dems have a realistic chance of making gains. Edinburgh Northern & Leith could be one place for the Lib Dems and Perthshire South & Kinross-shire is possibly a seat that the Tories could take. North East Fife and Ettrick, Roxburgh & Berwickshire are those rare seats where the Lib Dems and Conservatives are 1st and 2nd so deciding whether that will remain the case or whether SNP/Labour will charge through on Thursday is less easy to predict, something that I will conveniently avoid doing.

The Lib Dems sit 3rd/4th in a massive 21/36 seats which doesn’t lend itself to bar chart production. One can only wonder what graphic delights are taking place across the country. I suspect they are going heavy on the local policing pledge to fill that bottom corner of their leaflets.

Assuming (in line with recent polls) that the four main parties will score SNP 42%, Labour 34%, Tory 12%, Lib Dems 7% and applying the national swing to each constituency then the weighted average positions will become:

SNP – 1.43th
Labour – 1.90th
Tory – 3rd
Lib Dems – 3.66th

Labour will hold onto 28 seats, the SNP will be up to 43, the Lib Dems will have held onto 1 and the Tories will be on 1. Now, I don’t the above result will happen this Thursday but it does highlight the dominance that the SNP could potentially start to enjoy and the risk that the Lib Dems face of dropping into the dreaded ‘other party’ territory.

With four more years of an unpopular coalition and SNP candidates sitting 1st or 2nd all across Scotland, the Nats really could have two bites at the independence cherry over the coming years. A referendum in this coming term or an out-an-out majority from 2016.

Looking not so far into the future though, the above post serves one key message for me and that is that, if a significant tranche of voters have not decided who to vote for and if many of them tend to only chooce between the notional 1st and 2nd candidates, then the SNP could yet be runaway winners.
