Latest results from Tom Rice:
67 percent of votes are counted, Nutter has 68,000 votes and Knox 54,000. Bob Brady (34k) and Chaka Fattah (25k) follow.
Saint Joseph's professor Randall Miller checks in with some off the hip analysis.
He sees Nutter surging, but tempers that with the fact that it doesn't look like many West Philly (read: Jannie Blackwell) divisions have reported.
"It ain't over, but as of right now it looks like basically a two-person race with Brady being something of a spoiler in some places," Miller says. "If he spoils anyone it's Knox."
