The Golden State Warriors in 2017 and 2018 beat the Cleveland Cavaliers for the NBA championship (the teams squared off four straight times starting in 2015, with Northern California fans getting a trophy in three of those seasons). The Dallas Cowboys beat the Buffalo Bills in the 1993 and 1994 Super Bowls. The New York Yankees won the 1977 and 1978 World Series over the Los Angeles Dodgers.

While championship round rematches are relatively rare in sports — as the stats about professional basketball, football, and Major League Baseball reflect — they happen even less in their political equivalent, presidential campaigns. But eventually, they do happen, and this is the year, with President Joe Biden set to face his vanquished 2020 Republican rival, former President Donald Trump.
