7:04 | Possum - If it's the 22 *most* marginal then the swing is effectively zero. If it was the 22 most marginal Labor held seats, then the swing is effectively 2%. Accounting for a slight proportional application of swing (where larger margins swing larger against etc) and blow it up to a 3% swing, that would make the most probabilistic outcome to be Labour winning 53 seats if the polling is true. |
