While they don't show nearly as big a decline as they did with their Ohio gubernatorial numbers, Quinnipiac also has Democrats slipping in the Senate race. I'm prepared to believe that Democratic fortunes are really heading southward, but I do have to wonder if Q is overstating things. In May, they had Obama's job approval at 62-31 in the Buckeye State. Now he's at 49-44. Did his numbers really collapse so dramatically here, despite only a slight downtick nationwide? Perhaps, but I'd like to see confirmation elsewhere.
Anyhow, Quinnipiac has also started testing Tom Ganley's name - he's the wealthy car dealer who recently made his entrace into the race official. Portman has a 33-10 lead on Ganley in the primary. On the Dem side, Lee Fisher's lead over Jennifer Brunner has shrunk to 24-21 (from 31-26), with a lot more folks undecided than previously. With the primary still ages away, I don't think we can read a lot into these numbers.
