Hillary Clinton now leads Barack Obama in Ohio 49-45, according to a new poll from Quinnipiac (which will be posted here shortly).

That's a significant narrowing of her lead, and just barely outside the 3.5 percent margin of error. In a Quinnipiac poll released February 14, Clinton led 55-34 percent, and in a February 25 poll she led 51-40.

This poll includes Democrats and independents.

Among self-identified Democrats, Clinton leads with about the same margin--49 to 44 percent. Among independents who say they are likely to vote in the Democratic primary, Obama has a slight lead within the margin of error--50 to 48 percent.

Gender in Ohio displays the greatest divide. Women back Clinton 55-39, while men favor Obama by the same margin, 55-39.

UPDATE: Other polls show her lead holding or exanding slightly.
