In the 2020 presidential election, Trump made news after reports based on exit polls & actual election data showed his performance with minority voters being the second best of the modern era, only bested by Bush 2004.

However, there are signs that this is at least partly temporary. The same metrics show Ossoff and especially Warnock outrunning Biden with the state's nonwhite voters.

Gallup also showed Biden with only 12% (!) disapproval among nonwhite adults. Why did the minority vote shift back after moving towards the GOP in the presidential election?
