In light of new Forum Poll, Here's a Comparison of Some Other Polls...

A new poll from Forum Research was published in the Toronto Star this morning. It shows the Conservatives ahead by three point nationally over the Liberals and a tied race for third place between the Greens and NDP:


Forum joins the myriad of pollsters that have all measured a tightening race over the course of the summer.

Additionally, it has been documented on several occasions on this blog, Forum has polled the Conservatives much higher than other pollsters in the past two years (see meta-analysis here), so it surely is interesting to see Forum's numbers get closer to the field.

In fact, over the last two years, Forum poll's were consistently way off the 338's polling average. So here's a fun little graph: let's show not the average skew (like it was presented in the aforementioned meta-analysis), but the skew of individual polls from the middle of the poll's field date.

Goodbye July, welcome August.
