Obama is leading McCain 48-39 in a PPP poll released today (crosstabs after the break). This is the largest lead he has had in the state and the first one that is outside the MoE.
Obama is obviously doing well in Michigan, but PPP also pegged him with a 11 point lead in neighboring Ohio. On the other hand, Rasmussen gives him only a +3 lead in Michigan and a -1 loss in Ohio. This is good news but there's still a long way to go!
In other polling news, Rasmussen's daily tracker has Obama with a national lead of 49-43 and Gallup has Obama with a slight lead of 46-43.
