To determine the index, we used five races, two of which yielded losses for Republicans (2006 Attorney General, 2008 Presidential), two of which yielded wins for Republicans (2004 Presidential, 2006 Auditor), and one that yielded a plurality for Republicans (2010 Gubernatorial).

Using the Ohio Campaign for Accountable Redistricting's own scoring, these districts yield 10 competitive districts (45.0% - 55.0% Index).

Under the current map that passed in 2001/2002, voters gave Democrats a 10-8 congressional advantage in 2008 and Republicans a 13-5 advantage in 2010. Therefore, according to H.B. 369, each party loses one seat, respecting the voters' decision about what their congressional delegation should look like.
