Barack Obama 48
John McCain 40
For the second month in a row Barack Obama has a solid lead in PPP's Ohio tracking poll.
His 91-6 lead among black voters in the state is not a big surprise, but he is also keeping it surprisingly competitive among white voters with whom he trails John McCain only 46-42. Whether he is able to keep the white vote this close will determine if he pulls off the victory in Ohio this fall or not.
Also of note is that despite losing the Ohio primary by a good margin, Obama is doing a pretty good job of keeping Democratic voters in the fold. He has a 77-11 lead with them, almost as good as the 83-12 edge McCain is showing with Republicans. Obama has a slight 42-37 advantage with independents.
