Assuming VPs are are included you do have to go back to the 1976 election to find a Bush, Clinton, and Biden free ballot
- Jimmy Carter (1977–1981)
- Ronald Reagan (1981–1989) (George HW was VP )
- George H. W. Bush (1989–1993)
- Bill Clinton (1993–2001)
- George W. Bush (2001–2009)
- Barack Obama (2009–2017) (Joe was VP)
- Donald Trump (2017–2021) (Hillary was on the ballot)
- Joe Biden (2021–present)
