The 2018 United States state legislative elections were held on November 6, 2018, for 87 state legislative chambers in 46 states. Across the fifty states, approximately 56 percent of all upper house seats and 92 percent of all lower house seats were up for election. Additionally, six territorial chambers in four territories and the District of Columbia were up as well.
Democrats flipped at least 350 state legislative seats, [2] picking up most of those seats in states where President Trump's approval rating was relatively low. [3] Six chambers—the Colorado Senate, New Hampshire House, New Hampshire Senate, Minnesota House, Maine Senate and New York State Senate—flipped from Republican to Democratic control. [4] Additionally the Connecticut Senate went from being evenly divided to a Democratic majority. [4] Democrats also broke Republican legislative supermajorities in North Carolina, [5] Michigan and Pennsylvania [3] and gained a legislative supermajority in both houses of the California, Illinois and Oregon legislatures. [6] [7]
Regularly-scheduled elections were held in 87 of the 99 state legislative chambers in the United States; nationwide, regularly-scheduled elections were held for 6,064 of the 7,383 legislative seats. Most legislative chambers held elections for all seats, but some legislative chambers that use staggered elections held elections for only a portion of the total seats in the chamber. [8] The chambers that were not up for election either hold regularly-scheduled elections in odd-numbered years, or have four-year terms and hold all regularly-scheduled elections in presidential election years.
Note that this table only covers regularly-scheduled elections; additional special elections took place concurrently with these regularly-scheduled elections.
