Until 1968, presidential candidates were picked by party conventions - a process revived by Biden's withdrawal from race

Joe Biden has withdrawn from the 2024 presidential race and endorsed Vice President Kamala Harris as the Democratic nominee. The final decision will be made by Democratic National Convention delegates, as this will be the first major party nominee selected outside of the primary and caucus process in over 50 years. Some Democrats are concerned that letting the convention delegates, most of whom originally supported Biden, choose the nominee could seem undemocratic and illegitimate.
