The current Ohio Congressional District map demonstrates gerrymandering.

Much is often said about the impact of who gets to draw the congressional district lines every 10 years; so we took a look at history and found it really does matter.

After the 2000 Census, for the first time in 50 years, one party in Ohio controlled the entire process – both chambers of the Statehouse and the governor’s office.

The Republicans, with that full control, drew the lines and won 62 percent of the congressional races in Ohio from 2002 through 2010 despite winning only 51 percent of the overall vote.

Read our findings. It will be interesting to see whether the GOP enjoys the same kind of success from their new lines for  2012 through 2020. The lines were again drawn with the Republicans holding full control of the process.
