ABC News speculates on the Obama coattail effect for Kay Hagan:
But a large turnout of early African-American voters in North Carolina offered an indication that Sen. Barack Obama's relentless campaigning in the state may have paid off for Hagan.
"This is an example of a Democratic senator riding on Obama's coattails," said Jennifer Duffy, the senior editor at The Cook Political Report. "At least 500,000 early voters have been African-American, and Elizabeth Dole isn't getting those votes."
Worth pointing out that Hagan is running ahead of Obama. That may be as much because of their opponents: McCain-Palin was more popular in the end than Sen. Elizabeth Dole.
Still, there's no doubting that Hagan benefited from Obama voters.
