In 1976, the Democratic-Farmer-Labor (DFL) was Minnesota's dominant political party. It held two U.S. Senate seats, the governor's office, four of eight Congressional seats, 104 of 134 seats in the Minnesota House of Representatives and 49 of 67 seats in the Minnesota Senate. In 1978 the DFL suffered devastating losses in what is known as the "Minnesota Massacre." The two U.S. Senate seats and governorship went Republican, Republicans picked up an additional Congressional seat, and the DFL lost its majority in the state House, ending up with a 67–67 tie. (The Minnesota Senate was not up for election in 1978.)
