A Labour source says the results of the latest Sharp End poll call into question Plaid Cymru's stated aim of boosting its constituency vote in future Assembly elections and particularly leader Leanne Wood's decision to fight a constituency rather than a regional seat in 2016.
The poll suggests that Plaid's support in the constituency vote has dropped by 2% since the 2011 election although its since an increase of 8% in the regional vote. Plaid says 'it's very pleasing to see (the party) leading the votes on the National Assembly regional list.'
But the Labour source tells me that Plaid should be worried:
Leanne’s decision to stand in a constituency seat looks like it will come back to haunt her.
Plaid’s entire assembly election strategy is based around winning constituency seats. This poll suggests that strategy is destined to fail.
