Yes, her final margin was something like 4 points. The polls had her up something close to 10 in the final week.
On the other hand, I wouldn't put too much into just one poll at this point--polls can oversample Republicans just as they can oversample Democrats.
But it's better than that sloppy Free Press poll splashed across the front page yesterday showing a double-digit Granholm lead. That one was clearly tilted, and probably for political reasons.
I found that result to be stunning given Posthumos' lack of name recognition and Granholm's camera friendly profile. With the economy what it is here now I find it hard to believe that Granholm and Stabenow have the leads recent polls have indicated.
