Depending on who wins in Georgia for the Senate Runoff election of 2021, what would that mean for the incoming Biden/Harris administration?

Georgia is holding two runoff elections for U.S. Senate on January 5, 2021, as no candidate received a majority of votes in either the regularly scheduled election or the special election on November 3, 2020. Georgia was the only state to hold two U.S. Senate elections in 2020. The special election is being held to fill the rest of retired Sen. Johnny Isakson's (R) term.

The runoff elections will determine which party has a majority in the U.S. Senate. Democrats need to win both seats to split control of the chamber 50-50. The vice president (Democrat Kamala Harris beginning in January 2021) casts tie-breaking votes in the Senate. Republicans need to win at least one seat to maintain their majority.

David Perdue (R) and Jon Ossoff (D) are running in the regular election. Incumbent Kelly Loeffler (R) and Raphael Warnock (D) are running in the special election. See below for candidates' backgrounds and key campaign messages, along with in-depth coverage of each race.
