I always wonder just who was polled, how the poll was worded and how the results were altered to obtain the desired result.
During my lifetime, my ratings are:
1. Reagan
2. Trump
3. Eisenhower
4. Nixon (in spite of his many flaws)
5. Bush the Younger (in spite of his flaws)
6. Kennedy
7. Bush the Elder (because of his flaws; he should have beaten Clinton)
8. Clinton
9. Johnson
10. Carter (Carter wins as the worst ex-president to date)
11. Obama
