By nature of Joe Biden’s victory over Donald Trump in the 2020 presidential election, California Sen. Kamala Harris will now vacate her Senate seat to become vice president.
What happens to her seat is entirely up to California Gov. Gavin Newsom.
According to a 2018 report from the Congressional Research Service, California is one of 36 states where if a vacancy occurs, a new senator will be appointed by the state’s governor, with the interim senator serving until whichever comes first between the end of that Senate seat’s term or the next statewide general election.
In this particular case, Harris’ seat comes up for re-election in 2022, which is also the date of the next statewide general election. So whomever Gov. Gavin Newsom appoints will not face the voters until the 2022 midterms, when Newsom himself will be up for re-election. Read from source….
