For the second time this election season, U.S. Rep. Todd Rokita was nominated as the GOP candidate for the 4th District. The Indiana Republican Party held a special caucus on Saturday morning to refill the spot that was left vacant last month after Rokita attempted to replace Gov. Mike Pence’s position as the Republican gubernatorial candidate. “I know we’re here, really, because I filled out a form to declare vacancy for this position after 69 percent of the people — Republicans — voted for me in the primary. And I feel I owe a little bit of an explanation,” Rokita said to the voters gathered at Faith East Community Center.
