Look how the votes have changed this year compared to last (using the BBC’s national equivalent vote share projections, i.e. this is comparing like with like as it adjusts for the different range of seats up for election):
- There’s a good follow up piece by John Rentoul over on the Independent website.
- I thought the text in brackets at the top of this post was pretty clear… but judging by some of the reactions to this post along the lines of ‘OMG! That can’t possibly be true! You’re not comparing like with like!’, it’s worth emphasising the point again – these figures are about what has happened to the levels of support for parties in 2013 compared with 2012. The figures take into account the different range of wards up for election last year and this as they are national equivalent vote share calculations. This post on the LSE site has a good introduction to what those calculations are and what they mean.
