That is a Zogby “online” poll... I wouldn’t take it as very useful. The first good read is going to come on this Thurs/Fri polls, after the weekend effect is worked out.
To be more precise, it is a Zogby 'interactive' poll. He has a group of internet contacts for which he has demographic info, then invites a representative sample to participate. Not like the internet polls we wee so often.
