I have very little trust for pollsters and polls. I know how easy it is to use polls for propaganda purposes. I also realize that the other Zogby brother was involved with the Gore campaign.
That said, I still don't see any signs at this point that John Zogby and his brother are part of a conspiracy to advance the Muslim cause just because their heritage is Arab. The Zogby's are Christian. His desendants most likely left the M.E. because of Chritian prosecution by Muslims.
John Zogby has many customers around the world. We all know that he has a fairly good polling track record. Apparently, he even factored in the voter fraud in the 2000 presidential election as we were all criticizing him here at FR.
I would have to see specific Zogby push polls before I could come to a conclusion that Zogby is part of a "plan" to turn our country into a Muslim country.
