“Zogby Interactive = internet poll.”
Yes, and they have been working this method, to refine it into an accurate means of polling.
What is the difference, between making telephone calls, and asking people to respond to online questions?
I participated for quite awhile, when invited.
The fact Zogby, Gallup, Pew and Rassmussen have the same trend, means it is a true trend.
Is participation in the poll by invitation only, or do the participants self select?
