Iowa’s tightly contested U.S. Senate race between Rep. Ashley Hinson (R-IA) and Democratic state Rep. Josh Turek, which has been largely shaped by the Hawkeye State’s sizable agricultural economy, may be the deciding race to determine whether Democrats are able to take a majority in Congress after the November midterm elections.

Hinson and Turek are in a dead heat to replace outgoing Sen. Joni Ernst (R-IA). According to the RealClear Politics average of the latest polls, Turek has a 1-point lead over his Republican opponent, well within the margin of error.
