In the past Zogby polls have been a joke. This season (mostly) they seem not too crazy, but you dont know if it is the broken clock effect or are they actually getting better.
I think Zogby was "ahead of his time" in trying to do online polls for elections as far back as 2004 when that methodology was still in its infancy and the online panels had all kinds of skews. Its now 2012 and the online panels are vastly better and more reliable - so i don't think there is any reason to believe Zogby is less reliable this year than anyone else doing online polls
