Yesterday's Roy Morgan poll has National's lead increasing by over 5% as the Labour Party suffers from that most dreaded political condition - Electile Dysfunction, otherwise known as Sagging Support Syndrome. There is no medication available. This condition is beyond even Viagra and Niagra.
So, which poll is wrong? One of them sure as hell is and for my money I reckon it's the Herald. They've been wrong before (Epsom) and they don't tell us how many people were sampled. Roy Morgan is more upfront and 1,588 people were sampled.
Anyway, I like the Roy Morgan result so the other bastard must be the rogue.
Update: So far (0800) Adolf can find no reference to the Roy Morgan poll in any of the Antique Media.
Update: (0955)A commenter at Farrar's place identifies the DigiPoll sample as 600. Need I say more?
