Is there a Poll out tonight?

Back in 1992, John Major’s led a Government with a c20 seat majority. But the cumulative majority of those 20 seats was just 2000 votes.

Two Thousand votes in the right places out of 45 million cast determined the fate of the Government. Of course, you can never predict such narrow margins, which is why we were all probably nuts to even try to predict seat numbers.

The narrowness of the majorities in the top 50 seats means that, despite polling 2,207,400 votes more than Labour and 3,980,917 votes more than the LibDems, on Thursday night the Tories [10,808,749 votes] just missed-out by a whisker. 10,000 votes in the right place would have swung-it for them.

Just 1000 votes in the right place take us to seat 11 - Solihull
Just 2000 votes in the right place take us to seat 16 - Mid Dorset & Poole
Just 5000 votes in the right place take us to seat 24 - Swansea West
Just 10000 votes in the right place take us to seat 33 - Great Grimsby
Just 20000 votes in the right place take us to seat 44 - Morely & Attwood
Just 50000 votes in the right place take us to seat 65 - Newport East

But the battleground ahead will be more complicated than that. Each party will have its targets to win and targets to defend. So, I've created four tables - one for all parties and one-each for the main-parties showing their top-50 marginal seats. This is the4 list the party strategists will be looking at and deciding whether to fight [another party] or defend their own.

And one interesting fact to emerge from this analysis is that Ed Balls' seat is unique in that it turns out that he is the only one in the list to have been fought under the Lab-CoOp banner rather than The Labour Party. There were 16 of these Morley and Outwood; Luton South; Harrow West; Feltham and Heston; Cardiff South and Penarth; Barrow and Furness; Liverpool Wavertree; Nottingham East; Ilford South; Preston; Edmonton; Kilmarnock and Loudoun; Islwyn; Rutherglen and Hamilton West; Glasgow South West; Liverpool West Derby. Does this give us a hint of the Union influence to come?

These lists are fun but - especially after the swings we've just seen - no more than that, I think.

For example, Redcar is now "safer" than 30 other Lib Dem seats, yet ITIRIS that it wasn't really on anyone's radar beforehand.

It is also useful to show that the "they were lucky/unlucky" argument is fairly balanced: Tories hold 7 seats with knife-edge majorities under half-a-percent; Labour hold 6.

Expanding out to 2% (as for a 1% swing), 16 Tory seats to 14 Labour (and five Lib Dem). Haven't bothered looking at other sizes, but it does suggest that for every Hampstead & Kilburn, or Ashfield, there'd be an OxWab or Thurrock (pretty much).
