This is the second time in just over a year that we've been asking the question: "Why did the pollsters get it so wrong?" They got their prediction of the result of the 2015 General Election so wrong. They predicted there would be a Hung Parliament, like at the the 2010 General Election, and the formation of another Coalition Government (we had a Tory/Liberal Democrat coalition between 2010 and 2015). People were saying we may get a Tory/Ukip coalition or (something too horrific to even contemplate) a Labour/SNP/Green coalition. Instead, the Tories ended up winning outright, their first outright win in a General Election since 1992.
