A Pew Research Center poll conducted in mid to late June has Barack Obama leading John McCain nationally 48 to 40. Obama is faring better with under-50 voters than John Kerry was at this point four years ago; is still weak with over-65s. About 30% of former Clinton supporters are resistant to Obama (i.e., PUMAs). A steady and dependable 12% of voters still insists on believing Obama is a Muslim with ulterior motives. A third of registered voters say they are undecided or may change their minds. But two new Zogby International polls have Obama leading McCain in the must-win states of Pennsylvania by 10 points and in Michigan by 14 points. So things are looking okay or at least decent for the most part. But don’t get cocky.
