Obama also leads among women and Latinos — no surprise there either — but Romney's 0 percent can't help but stand out.
On a larger scale, the latest NBC News/Wall Street Journal poll has an Obama-Biden ticket at 48 percent approval, and a Romney-Ryan ticket at 44 percent approval. July's poll was 49 to 43, suggesting that little has changed.
In a smaller poll conducted among voters in 12 swing states, Obama had a three-point lead over Romney.
The groups Romney still leads in: rural voters, senior citizens, and white people.
