Opinium publish their historic polls

Notice how others are large – like Angus Reid

The new kid on the polling block, Opinium, has published its historic polls and it is interesting to track how it compares with everybody else.

The striking feature for me is that it consistently has a high share for others – very much in line with the PB/Angus Reid polls. Maybe it’s something about online polling?

A disappointment is that it makes no attempt to politically weight its samples. This probably explains the relative volatility in its headline numbers

Their arrival brings to ten the number of pollsters that will be covering this election – which must be a record by a long way.
