Here is Bill White (MD – LucidTalk) talking about the South Belfast tallies from the general Election 2015. Tallying at the count is a bit like an exit-Poll and is a very accurate way of predicting the result several hours before the official result announcement. More importantly it shows the patterns of support for each party in various parts of the targeted constituency.

How did the pollsters get the main prediction of the UK General Election wrong? – although they got a number of things exactly right e.g. collapse of the Lib Dem’s, UKIP’s 12% vote share and the SNP dominance in Scotland. Here Peter Kellner – President of YouGov offers his views.
