During the final Democratic primary debate in March, Joe Biden pledged that if he were to win the party's presidential nomination, he would choose a woman as his vice-presidential candidate.
A lot has happened since then, not the least of which is Biden securing the required Democratic Convention delegates to become his party's presumptive nominee. Even before that point, however, speculation swirled around a dozen or so contenders to be Biden's running mate.
Buzz around the various candidates has risen and fallen as the nation has been buffeted by a viral pandemic, economic disruption and mass protests and racial tension.
