Politico - in a short item, this quote -
Harris has kept any considerations about political future close to the vest, but she has told advisers and allies to keep her options open, POLITICO reported in November. There are essentially three options for Harris: run for governor of California in 2026, run for president again in 2028 or decline to run for office and be a leader of the party from the sidelines.
A fourth option, in light of the election outcome, is to spend more time with her family.
