In his closing statement, Cruz talked about winning the Iowa caucuses. Trump had been leading the polls there for weeks before caucus night, but he ended up coming in second to Cruz. "I campaigned in the state of Iowa foursquare against the ethanol mandate, something everyone said was political suicide," Cruz said. "My two leading competitors both attacked me for it, the governor of the state said vote for anyone but Cruz, and lobbyists spent millions of dollars on attack ads," he continued.
