Biden is embattled on all fronts – from a stalled domestic agenda to international order – but a supreme court pick is an enduring act

Two years ago exactly, Joe Biden stood on a debate stage in Charleston, South Carolina, his candidacy on the ropes, and made a promise: if elected president, he would nominate the first Black woman to the supreme court.

Days later, Biden won the South Carolina primary on the strength of his support among Black voters. The victory propelled him to the Democratic nomination and then to the presidency. Last month, Justice Stephen Breyer announced his retirement, presenting Biden with an opportunity to fulfill that campaign commitment.
