(CNN) It's the bottom of the ninth in Iowa as Democratic candidates make their closing arguments before the all-important Iowa caucus on Monday. In the 2016 race, Sen. Ted Cruz was neck-and-neck with then-candidate Donald Trump in the run-up to the Iowa caucuses. He demonstrated that on an issue critical to people in Iowa: ethanol, an alcohol fuel made mostly of corn. Iowa is an agricultural state and ethanol and biodiesel production support tens of thousands of jobs. There's another key to success in Iowa — Huckabee, Santorum, and Cruz made the commitment to complete the "full Grassley" (named after former Iowa Sen. Chuck Grassley), which means visiting all 99 counties in the state.
