On 3 December 2019 Senator Kamala Harris ended her campaign for the 2020 Democratic presidential nomination.

Context

Polling and money sat. Neighbouring 2020 VP pick is 11 August 2020.

11 August 2020 VP selection is neighbouring. 2024 nomination is a different cycle.

The Vice President of the United States presides over the Senate, casts tie-breaking votes, and carries delegated White House portfolios. She does not write House bills, CBP operational orders, or Federal Reserve rate decisions. A vice president is not co-author of every presidential statute.

Why it matters

The path is political polarisation and democratic contest: a completed early exit is a dated campaign instrument, not a welfare series by itself.

What the sources establish

Established: 3 December 2019 withdrawal, independently reported.

Not established: that the 2020 ticket was thereby written, or a unique later turnout coefficient from that Tuesday.

Donors and voters had not consolidated. Biden later picked her.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Harris withdraws from the 2020 Democratic presidential primary, not a later speech about Harris withdraws from the 2020 Democratic presidential primary.

Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to She ended her campaign. Donors and voters had not consolidated. Biden later picked her. That limit is the alternative to treating office-holding as authorship of every later series.
