Here's a list starting with Washington which assumes that, following the death of an incumbent, his successor would be whoever won the following election IRL. The only exception to this rule is Hoover, who I picked to succeed Harding since a 41-year-long Hoover presidency is interesting to ponder LOL
1. George Washington; 1789-1799
2. Thomas Jefferson; 1799-1826
3. Andrew Jackson; 1826-1845
4. James K. Polk; 1845-1849
5. Franklin Pierce; 1849-1869
6. Ulysses Grant; 1869-1885
7. Benjamin Harrison; 1885-1901
8. Theodore Roosevelt; 1901-1919
9. Warren Harding; 1919-1923
10. Herbert Hoover; 1923-1964
11. Richard Nixon; 1964-1994
12. Bill Clinton; 1994-present
The alternative is a 50-year Carter Presidency:
10. Calvin Coolidge; 1923-1933
11. Franklin D. Roosevelt; 1933-1945
12. Harry S. Truman; 1945-1972
13. Jimmy Carter; 1972-
2023, probably
