The runoff election between Perdue and Ossoff was on January 5, 2021, alongside the
special election for the other Senate seat held by Republican
Kelly Loeffler, to fill the remainder of
Johnny Isakson's unexpired term (which expired in 2023). Loeffler was defeated by
Raphael Warnock in that special election. Following the 2020 Senate elections, Republicans held 50 Senate seats and the Democratic caucus 48. Since Democrats won both Georgia runoffs, their caucus gained control of the Senate, as the resultant 50–50 tie is broken by Democratic vice president
Kamala Harris. If the Democrats had lost either race, Republicans would have retained control of the Senate. The high political stakes caused the races to attract significant nationwide attention. These elections are the third and fourth Senate runoff elections to be held in Georgia since runoffs were first mandated in 1964, following runoffs in
1992 and
2008. It is also the third time that both of Georgia's Senate seats have been up for election at the same time, following double-barrel elections in
1914 and
1932. The deadline for registration for the runoff election was December 7, 2020. Absentee ballots for the runoff election were sent out beginning on November 18, and in-person voting began on December 14. Ossoff's runoff campaign largely focused around accusing Perdue of corruption as well as aggressively courting Black voters in an attempt to drive up turnout, while Perdue characterised Ossoff as a
socialist and accused him of having ties to the
People's Republic of China. Perdue's campaign was hampered by his refusal to state that
Joe Biden had won that year's
presidential election, which made it exceedingly difficult for him to argue that an Ossoff victory would create a Democratic
trifecta. As Ossoff and Warnock were both sworn in on January 20, 2021 shortly after the start of the
Biden administration, Ossoff became Georgia's senior senator and Democrats simultaneously held both of Georgia’s U.S. Senate seats for the first time since 2003.
