Best known as an interpreter of the political scene, Zogby had a brief stint as an aspiring politician himself in 1981, when he ran unsuccessfully for Mayor of Utica, New York. He describes himself personally as a Democrat, while his polling firm is “independent and nonpartisan”.
Since May 2005, he has been a contributing blogger at The Huffington Post.

With Zogby’s leftest leaning, it would be hard to convince me there is no politics in his polling.
I think many of the polls are politically driven.
