Three legislative chambers in two states, New Jersey and Virginia, held regularly scheduled elections.
As a result of the elections, New Jersey retained its Democratic trifecta, while a divided government was established in Virginia, as Republicans won back the lower house of the Virginia legislature, which they lost two years earlier.
Nationwide, regularly scheduled elections were held for 220 of the 7,383 legislative seats.
Delegates are elected to two-year terms in single-member districts.
Various states will hold special elections for legislative districts throughout the year.
