It's within the margin of error, to be sure, but Zogby's daily tracking poll is out this morning, and it gives Obama his first lead in Ohio in any poll, 47-45.

Meanwhile, Quinnipiac has Hillary up four points, 49-45, although that's down from her 11 point lead of a week ago.

Late Update: This throws a monkey wrench in the "Obama zeroing in on Hillary in Ohio" narrative. Rasmussen shows Hillary widening her lead by four points since their last poll, on Friday. She now leads 50-44.

Later Update: Ditto with the new poll from Public Policy Polling. It shows Hillary widening her Ohio lead from 4 points to 9 points.
