Will Biden leaving send the Democrats into chaos?

After weeks of speculation and acrimony, President Joe Biden has abandoned his bid for re-election, and endorsed his Vice President Kamala Harris to be his successor.This scenario has happened once before - late in the election cycle, a President bailed out and tried to hand over power to their Vice President. The subsequent chaos at the 1968 Democratic convention is legendary, and is something the party will be desperate to avoid in 2024.
