Biden wins all six Reverse-Pivot Counties that voted McCain-Romney-Clinton


Following the 2016 presidential election, Ballotpedia identified six Reverse-Pivot Counties that voted for Hillary Clinton (D) in 2016 after voting for John McCain (R) in 2008 and Mitt Romney (R) in 2012. 

All six of 2016’s Reverse-Pivot Counties voted for Biden in 2020.

These counties have a median population of 785,915. Voters there cast 4,015,613 ballots, representing 2.5% of all votes cast in the 2020 presidential election. All six are located in or near major metropolitan areas: Los Angeles, Atlanta, Baltimore, and Houston.

As of Dec. 11, Joe Biden (D) won all six of 2016’s Reverse-Pivot Counties by an average margin of 14.54 percentage points, roughly triple Clinton’s average margin of 4.96 in 2016.

The shift represents a continuing trend in these counties from supporting Republican presidential candidates towards supporting Democrats. Since 2008, when McCain won these counties, margins of victory have shifted 20.18 percentage points from Republicans to Democrats, on average.
