Big smile.

Sen. Barack Obama leads Sen. John McCain by 46% to 39%, according to a Fox News poll of registered voters.

Key findings: "Obama's advantage comes mainly from doing better among women, blacks, young voters, those with a college degree, and unmarried voters. He has increased his edge over McCain among women to 16 percentage points, up from a 4-point edge last month."
