Two Minnesota special elections in heavily Democratic Twin Cities-area state legislative districts will decide control of the state's House of Representatives for the third time in less than a year. Republicans hold a 67-65 advantage in the chamber after two Democratic representatives were elected to other offices in November. The chamber has operated under a power-sharing agreement between the two parties for much of the last year. Tuesday's contests take place just days after a U.S. Border Patrol agent fatally shot a man in Minneapolis, sparking protests and renewed calls for federal immigration officers to leave the state.
