I trust Newsweek more than John Zogby. Zogby is a pollster who has a pony in the race, too. What a joke all these polls are. My main test is the behavior of both campaigns acting in response to their internal polling. That's the best predictor for me.
See my post above, and see what you think. I don't trust any of them myself, I prefer to look at the averages of them all. Newsweek/Princeton on the other hand, I don't even include in my considerations. Didn't do it a few weeks ago when they had Bush up by +11%, won't do it now that they "show" him down by 2.
