Supermajorities in the 2018 elections

See also:2018 election analysis: State legislative supermajorities andVeto overrides in state legislatures

Four full state legislatures saw changes in their supermajority status—typically when one partycontrols either three-fifths or two-thirds of a chamber—as a result of the 2018 elections. Democrats attained supermajorities in three full state legislatures (both chambers)—California,Illinois, andOregon.^[2] This added to their existing four supermajorities, giving them seven total. Republicans, meanwhile, entered the night with 17 full state legislative supermajorities and lost one—North Carolina.

Eleven individual chambers changed supermajority status, including those that contributed to changes in California, Illinois, Oregon, and North Carolina. All of the changes favored Democrats.

Because of these changes, one party has a supermajority in 23 of 50 state legislatures, two more than the 21 supermajorities heading into the night.

Depending on the state, supermajorities can do anything from overriding gubernatorial vetoes to convicting impeached executive or judicial officials to passing constitutional amendments to raising taxes. Most of these special actions are only available if a party has a supermajority in both chambers.

State government trifectas

See also:Gubernatorial and legislative party control of state government

Democrats emerged from the 2018 elections with a net gain instate government trifectas—where one political party holds thegovernorship, a majority in thestate senate, and a majority in thestate house in a state's government.Republicans retain a net advantage of eight trifectas over Democrats. The new trifecta count stands at 14 Democratic, 22 Republican, and 14 divided.

Entering the 2018 midterm election, Republicans had a +14 state trifecta lead: of34 states with trifectas, 26 were Republican and eight were Democratic. But after the votes were counted, Democrats increased their trifecta total with a net gain of six, and Republicans declined to 22 trifectas (a net loss of four). States with divided government (i.e., no trifecta for either major party) declined to 14.

This outcome is similar to the trifecta balance following the 2014 midterm election, which left Republicans with 24 trifectas, Democrats with 13, and 13 states with no trifecta advantage for either major party. After the 2010 midterms, 25 states had no trifectas, Republicans had nine, and Democrats had 16.

In two cases where Democrats gained trifectas, and in one case where Republicans lost a trifecta, Democrats won open gubernatorial races that had been vacated by Republican incumbents who could not seek re-election due to term limits.

The total number of trifectas—36—is almost in line with the 37 trifectas in 2013 and 2014, the most trifectas in recent history.

Change in state government trifectas, 2018 elections
Trifecta status	Before	After	Net
Democratic trifectas	8	14	+6
Republican trifectas	26	22	-4
Divided government	16	14	-2

The six Democratic flips from divided government to trifecta control in 2018 were in:

• Colorado: Democrats won control of the Colorado Senate.
• Illinois: Democrats won the governor’s office with businessmanJ.B. Pritzker (D) defeating incumbentBruce Rauner (R).
• Maine: Democrats won control of the Maine Senate and took the governor’s office with Maine Attorney GeneralJanet Mills (D) defeating businessmanShawn Moody (R) and state TreasurerTeresea Hayes (I). Incumbent Gov.Paul LePage (R) was term-limited, leaving the seat open.
• New Mexico: Democrats won the governor’s office with U.S. Rep.Michelle Lujan Grisham (D) defeating U.S. Rep.Steve Pearce (R). Incumbent Gov.Susana Martinez (R) was prevented by term limits from seeking a third term, leaving the seat open.
• New York: Democrats won control of the New York Senate.
• Nevada: Democrats won the governor’s office withSteve Sisolak (D) defeatingAdam Laxalt (R).

In each of the four states where Republicans lost trifectas the balance of power became divided:

• Kansas: Democrats won the governor’s office with State Sen.Laura Kelly (D) defeating Secretary of StateKris Kobach (R). Incumbent Gov.Jeff Colyer (R), who took office following former Gov.Sam Brownback's resignation in January 2018, ran for a full term but was defeated by Kobach in the August 7 primary, leaving the seat open.
• Michigan: Democrats won the governor’s office with former state Senate Minority LeaderGretchen Whitmer (D) defeating Michigan Attorney GeneralBill Schuette (R). Incumbent Gov.Rick Snyder (R) was term-limited, leaving the seat open.
• Wisconsin: Democrats won the governor’s office withTony Evers (D) defeating incumbentScott Walker (R).
• New Hampshire: Democrats won control of theHouse andSenate.

Overall, 10 total states saw a trifecta status change in some way.

• Colorado: divided government to Democratic trifecta
• Illinois: divided government to Democratic trifecta
• Kansas: Republican trifecta to divided government
• Maine: divided government to Democratic trifecta
• Michigan: Republican trifecta to divided government
• Nevada: divided government to Democratic trifecta
• New Hampshire: Republican trifecta to divided government
• New Mexico: divided government to Democratic trifecta
• New York: divided government to Democratic trifecta
• Wisconsin: Republican trifecta to divided government

See also:State legislative battleground chambers, 2018

Ballotpedia tracked 22 state legislativebattleground chambers in 2018.

Heading into the 2018 elections, Democrats controlled 10 battleground chambers and Republicans controlled 12 battleground chambers.^[8]

Democrats captured six Republican-held battleground chambers in the election—theColorado State Senate,Maine State Senate,Minnesota House of Representatives,New Hampshire House of Representatives,New Hampshire State Senate, andNew York State Senate.

Republicans did not capture any Democratic battleground chambers, but they did enter into a power-sharing agreement in theAlaska House of Representatives, which was previously controlled by Democrats.

Battlegrounds were chambers that we anticipated would be, overall, more competitive than other chambers and have the potential to see significant shifts in party control in the 2018 general elections.

Criteria for identification as a battleground chamber included the majority party's share of seats, the number of competitive races, and more.Read the complete list of criteria here.

These were the 22 battleground chambers in 2018.

The columns in the chart below list the following information:

• Seats up in 2018: This was the number of seats in the chamber that were up for election in 2018.
• Margin: This was the difference in seats between the majority and minority parties.
• Majority share of seats: This was the percentage of the chamber's total seats controlled by the majority party.
• Last time party control changed?: This was the election where the party in power before the 2018 elections took control of the chamber.
