Ohio's 16th District
No individual House race is crucial, but many are important bellwethers, and the redistricting process throws a monkey wrench into the careers of many up-and-coming legislators. Take Ohio's 16th District, which will stretch from suburban Cleveland into the state's rural middle. In a rare occurrence, the race will pit two incumbent representatives from opposite parties against each other in a district that could go either way. Republican Rep. Jim Renacci, who was elected in 2010 and currently represents the 16th, will face three-term Democratic Rep. Betty Sutton, whose previous district based in Akron was effectively eliminated. Sutton, a rising star among Buckeye Democrats, was one of the principle authors of the "Cash for Clunkers" stimulus program.
