Sixteen state trifectas are vulnerable in 2020, according to Ballotpedia’s trifecta vulnerability rating system. Both major parties will be defending eight trifectas.
A state government trifecta occurs when one party holds the governorship and majorities in both chambers of the state legislature. There are currently 21 Republican trifectas and 15 Democratic trifectas. The remaining 14 states have divided governments.
Ballotpedia calculates the chances of trifectas breaking and forming by assessing the chances of each individual component changing control. We assess gubernatorial races with ratings from The Cook Political Report, Inside Elections, and Larry Sabato’s Crystal Ball. We assess state legislatures according to the absolute number of seats up for election and the proportion of seats that would need to flip for partisan control to change. Both chambers in a state’s legislature are evaluated individually.
Ballotpedia classifies the Democratic trifectas in five states as moderately vulnerable—Colorado, Connecticut, Maine, Nevada, and Oregon. Three Democratic trifectas—Delaware, Illinois, and New Mexico—are considered somewhat vulnerable.
The Republican trifecta in Florida is the only trifecta Ballotpedia rated as highly vulnerable this year. Four Republican trifectas—in Arizona, Georgia, Iowa, and West Virginia are classified as moderately vulnerable. The Republican trifectas in Ohio, South Carolina, and Texas are somewhat vulnerable.
Ballotpedia also assessed the chances of new trifectas forming in states that are currently under divided government. States that qualified as a possible Democratic trifecta pickup according to our methodology are Minnesota, Pennsylvania, and Wisconsin, while Republicans have pickup chances in Alaska and New Hampshire. In Montana and North Carolina, both parties qualify for a pickup opportunity.
