As Barack Obama closes in on the Democratic nomination, his prospects for November are looking up, a new poll indicates.

Obama, who was tied with presumptive Republican nominee John McCain last month in the same survey, now leads 48 percent to 40 percent, according to the Reuters/Zogby poll released today.

Obama builds his lead among independents -- 47 percent to 35 percent -- and also has an edge in who voters say would be better for the economy.
