Zogby has just released his poll from today and yesterday. Obama won Saturday 46-44. But he lost yesterday and only had 40%.
Zobgy sez Clinton 46-43 over Obama. Here is the poll.
But Zogby is not reliable. SurveyUSA has been very good. The PPP and the Q polls have been reasonably good too.
The real numbers, I believe, are to take the average of the good pollsters' numbers for Obama, and give all the undecideds to Hillary. This would yield an Obama number of 43-44, and give Hillary 55-54 (assuming 2% votes for someone else.) So, Hillary would win by 10-12%.
Even Zogby opines the undecideds will break for Hillary. But the good news is that Obama's support is not falling....
