The presidential vote swing in each county from 2016 to 2020. Note the large swing to the right in many Texas counties. Some of these are very small but some have over 50,000 people. They are mostly along the Mexican border (see below).
The below video shows the vote swing animated. The dots are colored by the direction of the change. Note that while there were large swings to the right in some Texas counties (see above) they did not necessarily flip their vote.
