A couple remarks on this very encouraging poll. First, PPP nailed Ohio in the primary even though it botched Pennsylvania. They know OH demographics at least.

There are some reasons to think this poll may have undercounted Obama's support. First, African Americans only support Obama 75-21. It will almost certainly be a wider margin than that - possibly 95-5. It also gives Obama only a 1-point lead among 18-29 year olds, a much smaller lead than among 46-65 year olds. This makes no sense either.

On the other side, the poll probably overstates his support among whites, showing him up by 4. That's quite optimistic.

The biggest oddity is party ID. It shows Democrats outnumbering Republicans 55-30. But we saw this with the SUSA poll of Ohio too, where the margin was 52-28.

I actually think this is plausible because it probably includes lots of Republicans and Independents who crossed over to the Democratic primary and still vaguely consider themselves Democrats for now. Many of those did so to vote for Clinton and so, not surprisingly, the percentage of Ohio Dems supporting Obama is lower than the percentage of Ohio Republicans supporting McCain. A lopsided party ID margin usually results in lots of "Dems" for McCain; the reality is many of these folks were probably Republicans who voted for Clinton in the primary (and not Limbaugh voters) but who never liked Obama. They were never really "Democrats" except for this primary.

If you remove these voters you'll find the party ID margin break closer to 50-50, but you'll see Obama getting well over 80% of Democratic support.

So watch for those party ID and party consolidation numbers. They are usually inversely proportional.

Either way, these are encouraging numbers for Obama in Ohio. He won't win Ohio by 11 points. But he looks stronger there at this point than he did a few months ago.
