From Mass. Numbers (October 31, 2014):
There are significant differences between IVR, live operator, and internet polls of the race for Massachusetts governor
As the polls of the race for Massachusetts Governor have steadily moved from a Martha Coakley lead in early September to a Charlie Baker lead in late October, a complicating factor has arisen: each of the three polling methodologies used to survey the race are showing different results. Interactive Voice Response (IVR) or robopolling firms show a reasonably large 5 point lead for Baker. Traditional live operator telephone polling shows Baker with a 2 point lead. And internet panel surveys show Coakley with a 4 point lead in the race.
It will be interesting to see how this plays out on Tuesday…
