Ukip’s 18 per cent debunked

Today YouGov released poll data that UKIP are on 14 per cent - something that wasn't news to me as this is exactly the same as the calculations I made last week. However the figure looks decidedly dodgy.

Today YouGov released poll data which had Ukip on 14 per cent – something that wasn’t news to me as it is exactly the same as the calculations I made last week.

YouGov’s poll comes after data published by ICM in the Guardian which claims Ukip has an 18 per cent vote share.

So how could Ukip achieve this much of the national vote share? This figure, too, looks decidedly dodgy.

If we take 31.5million or 66 per cent of voters as a likely General Election turn out, Ukip would need 5,670,000 to reach 18 per cent. Of that 31.5million, if Ukip polled a uniform 20 per cent or 3,700,000 across the roughly 18.5million voters who might turn out from the UK’s shires, towns and small and medium cities and combined that with 12.5 per cent or one million from eight million voters in the major cities Ukip would then need 970,000 or 19.4 per cent from Scotland, Northern Ireland and Wales to reach 18 per cent nationally.

Given that Ukip just don’t exist in Scotland, Northern Ireland and Wales, a 19.4 per cent vote share there is not only very unlikely it would be miraculous.

Give Ukip a more likely and still very generous 7.5 per cent in the major cities and five per cent in Scotland, Northern Ireland and Wales, and they would need 4,820,000 or 26 per cent across the rest of the country to make 18 per cent of the total vote share. Again, very unlikely.

Bring Ukip’s vote share down to the 4.16 per cent they achieved in Bristol – the only major city they’ve recently competed for the vote in – for the urban vote, totalling 330,000, and down to the 0.5 per cent or 25,000 vote share they took in Scotland, Northern Ireland and Wales in 2012, Ukip would be left needing 5,312,000, or 28.7 per cent in the rest of the UK, almost a full one per cent above what they polled in Eastleigh, to make the figure up to 18 per cent.

It just doesn’t stack up I’m afraid.

    It’s a strange world where comparing the Tea Party with UKIP is irrelevant, but comparing Farage to Gandhi isn’t.

    There is a serious point here which is that what’s happening with UKIP isn’t some brand new political phenomenon. It’s happened in numerous other countries – a populist, nativist movement springs up that can’t form a government by itself, but is effective at leveraging one of the main parties (the Conservatives in this case). What has also happened, in almost all of these cases, is that after some initial success the party/movement falls off the radar.

    We’re expected to believe that UKIP are different, yet every party in that mould has claimed they were different and almost all of them ended up the same way. When UKIP have broken new ground and formed a government – or even won a single MP – we can call it a revolution. We’re nowhere near that stage at this point.

    Not much hope of UKIP getting 5% of the vote in Scotland. For some reason, Scottish polling seems to have been fairly off-kilter in recent years. Before the last Holyrood election, the pollsters had Labour with a really solid lead over the gnats which was bewildering to anyone and everyone with an interest in Scottish politics. is there a flaw in methodology? Is it just plain bad luck with sampling?

    You’re comparing Nate Silver’s detailed, granular statistical analysis to a piece which basically says ‘I don’t believe the polls’?

    The Five Star Movement?

    They’ve still only contested one election, although I do think they’re a bit different as they’re a standalone movement rather than a party that’s effective at leveraging a bigger rival. They almost seem to dogmatically oppose any sort of co-operation with the major parties, whereas UKIP have actively encouraged the idea of joint-tickets with the Conservatives.
