All 80 seats in the General Assembly were up for election this year. In each Legislative district, there are two people elected; the top two winners in the general election are the ones sent to the Assembly. Typically, the two members of each party run as a team in each election. After the previous election, Democrats captured 48 seats while the Republicans won 32 seats.
Democrats flipped one seat in the 2nd district and Republicans flipped one in the 1st district, leaving the balance of power unchanged at 48âÂÂ32, despite Democrats losing the popular vote. This remains the last election in which the party that won control of the General Assembly did not win a majority of votes.
Summary of the November 5, 2013, New Jersey General Assembly election results:
Districts where the difference of total votes between the top-two parties was under 10%:
