Why were the polls so wrong?

Like Ed Miliband, pollsters also suffered a severe defeat last week. Far from the dead heat which the national opinion polls had predicted for months, David Cameron won by a heavy margin. But how did the pollsters get it so fundamentally wrong? Especially, when just yesterday, even Cameron thought a Conservative majority was near impossible.

After the exit polls blew months and months of pollsters’ predictions out the water, it became clear that the Tories had been radically underestimated. We thought that the race couldn’t be any closer but we were in fact wrong.
