Revised Welsh Assembly Forecast: The Constituencies

Having got wind of a poll taking place this week I held back from revising the Welsh Assembly forecast until it was released. It emerged from rmg:Clarity on Thursday but wasn't quite what I was expecting. Despite going through the considerable effort of getting a representative sample from all 40 constituencies they didn't ask separate Constituency or Regional Voting Intention. In fact it wasn't even clear that the VI question related to the Welsh Assembly, although you would hope that's what respondents thought of when they heard the words 'forthcoming election'.

The poll was of some use in that it backed up YouGov's current snapshot of a huge Labour lead at the expense of the Liberal Democrats and, more recently, Plaid Cymru. As such I've averaged the two March polls from YouGov to form the basis for the revised forecast. The key difference from the two forecasts is a 4 point drop in support for Plaid going almost directly to Labour. The Conservatives and the Lib Dems have remained fairly stable since the turn of the year.

So I'll go through the Constituencies region by region. There will be a second post up later today with the regions adjusted before a final fully revised forecast will be published this evening.

It's fair to say that Carmarthen West & Pembrokeshire South is beginning to look like a Labour gain. They require just a 0.2% swing to take this off the Conservatives and with current polling suggesting the CON>LAB swing is around 7% I'm pushing this into the lean Labour column. In addition, because of Plaid's drop in support they are looking a lot less likely to take this from third. Labour's recent boost in the polling has come at the expense of Plaid Cymru, which has made Llanelli look a lot tighter than it did in January. On uniform swing Labour gain this seat although Plaid's incumbency advantage should help them a little. Certainly Too Close on the current evidence.

As for Montgomeryshire, the recent polling has shown the Tories and Liberal Democarts virtually unchanged since January so I've left that as it is for now. The Lib Dems currently hold his on UNS but the previous incumbent's behaviour may harm their defence. Preseli Pembrokeshire is looking quite good for Labour but their margin on UNS isn't large. This is still looking close at the moment and a modest rise in the Conservative's, or a small drop in Labour's, polling would swing this back to them.

As for the other seats in Mid & West Wales, Plaid Cymru are still clear favourites in Ceredigion, Dwyfor Meirionnydd and Carmarthen East & Dinefwr. In the final seat the Liberal Democrats look like they have enough to see off the Conservative challenge in Brecon & Radnorshire, especially as the incumbent is their Assembly Leader Kirsty Williams.

In North Wales Aberconwy is still very tight. On UNS Labour gain this from third place but they were quite a way behind the Conservatives in second at the last election. The Tories should be able to use this to their advantage in the campaign. The seat is held by Plaid Cymru but they look like they are going to struggle here. The loss of their incumbent and their current polling suggests they are set to lose this seat. The question is, who to?! Plaid's drop in the polls has brought Arfon slightly in to play. Nationalist supporters shouldn't get too worried; unlike Llanelli they still win this on UNS. However, the polling suggests their majority will be cut to around 1000 votes so they can't be too complacent.

At this stage it is hard to imagine Labour losing any seats they won in 2007 and so Clywd South, where they are defending a 1119 vote majority, should now be considered safe. In Clywd West Labour need a 3.2% swing to gain the seat from the Conservatives, which they do so with ease on current polling. That's been moved from Too Close to Labour Lean.

The other five seats have been left as they are for now. Alyn & Deeside, Delyn, Vale of Clywd and Wrexham should all stay with Labour, although the latter three I'm leaving as Leans given how close they were last time. I think Ynys Mon still leans Plaid Cymru although Labour do get quite close on UNS. The fact the incumbent AM is Plaid's Assembly Leader Ieuan Wyn Jones should be enough to hold the seat.

South Wales Central

Constituency

Initial

Revised

Cardiff Central

Too Close

Too Close

LD/

LAB

Cardiff North

Too Close

Too Close

CON/

LAB

As we move around South Wales I have mostly changed Labour Leans to Labour Safes. I had factored in a higher than average LD>LAB swing in Cardiff Central due to the large student population so the fact Labour are now quite close to the Liberal Democrats here on UNS doesn't affect the forecast. Labour just manage to gain Cardiff North on Uniform Swing but the incumbency advantage the prominent sitting Conservative AM Jonathan Morgan should enjoy leaves this very much in the balance.

Elsewhere in South Wales Central I have moved Cardiff South & Penarth, Cardiff West and Pontypridd into the Labour Safe column. Cynon Valley and Rhondda were already there and as Labour are defending a tiny 83 vote majority in Vale of Glamorgan that has remained a Labour
Lean.

South Wales East

In South Wales East I consider Caerphilly, Islwyn, Merthyr Tydfil & Rhymney, Newport East, Newport West and Torfaen as safe for Labour. Monmouth is a safe seat for the Conservatives so that on leaves Blaenau Gwent as slightly in doubt. This very much leans towards Labour though.

South Wales West

In South Wales West Labour are virtually assured of all seven seats on the current polling. Which means Aberavon, Bridgend, Gower, Neath, Ogmore, Swansea East and Swansea West should all fall in the Labour column come May 5th.


We make no bones about the fact we are covering this election from the South West of England and so we may be missing developments on the ground in Wales. If you are out and about on the campaign trail then don't hesitate to disagree with any of our classifications! Look out for the Revised Regional projection later this afternoon. There is a surprise or two!

  1. My only observation would be in Carmarthen West, where Nerys Evans - the Plaid candidate - will pick up a lot of personal votes as an incumbent regional AM for Mid West Wales. I'm not sure if that's enough to give her the seat, but it could well take votes away from Labour and leave it with the Conservatives.

  2. Thanks Aaron. I have to say of only one seat is going to defy any UNS calculations CW&PE is it. However, plugging the current polling into UK-Elect gives the result in that constituency as: LAB 44, CON 27, PC 24.

    I think both Evans, as a high profile AM, and Burns, as the incumbent, will improve on that but they both have a lot of ground to make up on Gwyther to prevent a Labour gain.

    Still, a lot can change in 3 1/2 weeks!

  3. I'd be careful here with the aggregating -- polling houses, usually through no fault of their own but as the result of how they formulate questions or what time they make phone calls, can introduce slight party-political biases that Nate Silver of fivethirtyeight.com calls "house effects". If the rmg:Clarity poll consistently shows results more positive for Labour across Wales, it could be a shift toward Labour -- or it could just be that the way rmg:Clarity does analysis favors Labour a bit more than the way YouGov does.

    I didn't actually include the rmg:Clarity data in the averaging; just the two YouGov polls released in March. I'm of the opinion that YouGov itself has a house effect that favours Labour at the moment so I'm hoping an established phone pollster has a go before the election.

  5. If Plaid Cymru lose Arfon I'll eat my hat. Alun Ffred Jones is sitting on a 25% majority; Hywel Williams comfortably won the Westminster seat for Plaid despite everyone saying it would be too close to call. The town of Caernarfon has been represented by Plaid in Westminster since 1974; this trend isn't likely to be reversed in the Assembly, of all places.

  6. I wouldn't say that Hywel's win last year in Arfon was comfortable but I agree that Alun Ffred Jones is pretty much a shoo-in in Arfon. According to the Notice of Poll he is the only candidate in Arfon with an address in the constituency or indeed in North Wales! That will matter in Arfon.

    Carms West and South Pembs - Ladbrokes have got this right - Labour 4/6, PC 2/1, Con 9/2. Burns seems to have given up, not attending hustings. They will be pushed into third and this becomes a Labour/PC fight with Labour edging at the moment

    "Blaenau Gwent......slightly in doubt"??!!! If you can persuade a bookie of that then you should make a pile. Not even a Labour lean, it's a Labour topple over. 10,000 labour majority last May. Not even close

  7. Plaid 2/1 to take Carms West & Sth Pembs - bargain, I'm off down the bookies!

    This is a largely rural seat - Plaid's Nerys Evans is a high profile, well respected and well-liked local candidate, Labour's Christine Gwyther is the famously vegetarian former Agriculture Minister.

  8. You can get 10/3 for Nerys to win on Victor Chandler's site. Probably among the best odds around
