Ohio's President's: Why are They the Worse?

What makes Ohio's presidents considered among the worst ever. I believe through my research that Ohio's president's are considered the worst because even the highest ranked men didn't accomplish much during their presidency, while the others had scandals that plagued their term. From the Teapot Dome Scandal to the Panic of 1873 Grant, Harrison and Harding earn their place in the cellar of Ohio presidents where as even those who ranked higher can only go so high due to lack of accomplishment. Mckinley had a clean presidency, but didn't get much accomplished so he would never climb into the top 15. In todays times no president will probably crack the top 10 because presidents aren't viewed as highly as they one were and the times just lent themselves to letting a good president become a great president. I don't believe that Ohio's presidents overall were that terrible they just weren't the right men for the job.
