As a result of the 2019 elections, Democrats gained one state government trifecta in Virginia. A state government trifecta exists when one political party controls the governorship, a majority in the state senate, and a majority in the state house in a state's government. Republicans also lost a trifecta following incumbent Gov. Matt Bevin's (R) defeat in Kentucky. The new trifecta count stands at 15 Democratic trifectas, 21 Republican trifectas, and 14 divided governments.

Prior to the 2019 elections, Republicans had eight more state government trifectas than Democrats: of 36 states with trifectas, 22 were Republican and 14 were Democratic. Democrats saw a net gain of one trifecta and Republicans lost one trifecta. The number of states with divided government (i.e. no trifecta for either major party) remained at 14.

For comparison, following the 2017 elections, Republicans controlled 26 trifectas to Democrats' eight, leaving 16 states without a trifecta. Following the 2014 midterm election, Republicans had 24 trifectas, Democrats had 13, and 13 states had no trifecta advantage for either major party. After the 2010 midterms, 25 states had no trifectas, Republicans had nine, and Democrats had 16.

The new Democratic trifecta in Virginia was formed after the party won majorities in the state Senate and state House. Heading into the election, Republicans held a 20-19 majority with one vacancy in the Senate and a 51-48 majority with one vacancy in the House. Democrats won a 21-19 majority in the state Senate and a 55-45 majority in the state House.

The total number of trifectas—36—is the highest number since 2014, when there were 37 trifectas.
