The new Quinnipiac poll of Ohio shows Democrats starting out with a slight edge for the 2010 Senate race in this perennial swing state, which will be an open race for the seat of retiring GOP Sen. George Voinovich.

Both Democrats lead both Republicans, albeit by narrow margins. Democratic Lt. Gov. Lee Fisher leads former Rep. Rob Portman by 37%-33%, and he leads auto dealer Tom Ganley by 36%-30%. Democratic Sec. of State Jennifer Brunner edges Portman 35%-34%, and she leads Ganley 35%-31%.

In the Democratic primary, Fisher has 24% to Brunner's 21%, with "Undecided" way ahead with 51%. Portman leads for the Republicans with 33%, followed by Ganley at 10%, and "Undecided" at 55%.

Obviously, the undecideds are very high for all of the primary and general match-ups here, Ohio is a perennial swing state, and we're still very early in the cycle. So we'll see what happens as the race goes on.
