2022: Abrams beats Kemp in the gubernatorial election.
2024: Non-Trump Republican beats Biden.
2026: Abrams re-elected as governor.
2028: Republican President re-elected.
2032: Abrams wins presidential election.
2036: Abrams re-elected president.
So the only question is why didn't she run in 2028 - which I would guess is because the Republican president was somewhat popular or in a strong position and she thought she'd have an easier time running in an open race than against an incumbent.
Pretty much this. I think she would only successfully run for President if she managed to win the Governorship and prove that she's a unique political force, so that realistically means winning two terms.
