[Update]: According to the latest YouGov poll, the swing to the pro-EU parties from the Con/Lab relics has been even bigger than I’d allowed for in this analysis. So head here for the latest pro-EU Scottish tactical voting  recommendations. My previous recommendation was to swing to the SNP, but the figures now suggest that LibDem voters should stay where they are, and that any new swing voters should head for the Scottish Greens or indeed the SNP.

Voting based on the YouGov/TheTimes poll from the end of April would translate to 3 seats to pro-EU parties, 2 for pro-Brexit/anti-EU parties (1 Brexit and 1 Conservative) and 1 for Labour (whatever they are) – the d’Hondt model used in Great Britain  is pretty robust in that regard, favouring smaller parties as the count progresses.

A tactical voting model that favoured the SNP at the expense of the Lib Dems and Change UK and the Brexit party at the expense of the Tories and (to a lesser extent) Labour, would give the Scottish MEP list 4 SNP seats, 1 Labour and 1 Brexit, a majority of 3 or 4 for pro-EU candidates, depending on whether Scottish Labour was neutral or pro-EU.

A tactical voting model that favoured the smaller parties (some Conservative and Labour to Brexit and Remain vote from Conservative, Labour and SNP to the LibDems, Scottish Greens and Change UK) would also give four seats to pro-EU parties (two SNP, one Green, one Lib Dem) but would lose Labour its seat, give the Conservatives one and make no difference to the one seat that the Brexit Party would have, thereby reducing the Pro EU majority on the list from 3 or 4 to 2.

There’s been much speculation about the pro-EU parties combining their lists (I think it’s too late for that now). However, changes to the list where the smaller parties came together to combine their lists (LibDem + Change UK, LibDem + Change UK + Scottish Green, then Brexit and UKIP combining votes) actually makes no difference to the overall outcome in terms of Pro/Anti-EU representation. What it would do is gain the centrist alliance a seat at the expense of the SNP.

An alliance of Change UK and the LibDems, using the YouGov figures, would likely achieve no net change: they’d gain a seat at the expense of the Greens.

However, the Scottish Greens on their own have at least a chance of a seat on their own (but only within a 5% sensitivity analysis), so their incentive for cooperation is perhaps limited. As a still largely issue-driven party, their vote is probably also less susceptible to tactical defection.

Now for the detail… Continue reading Tactical Scotland →
