Math, microeconomics or criminal justice
Lincoln had his "cabinet of rivals"
Obama was praised for seemingly doing the same when he chose Biden as veep and Hillary as Secretary of Defense, using people who had run against him in the primary.
John Quincy Adams and Andrew Jackson, of opposite parties, and who hated each other intensely, had the same vice president, John C. Calhoun, that went relatively successfully. Adams said Jackson was unfit to be president. Jackson accused Adams of stealing the election in 1824.
Eisenhower chose Nixon as veep, to appeal to conservatives, but almost considered dumping him before the 1956 election. Liberal Earl Warren was IKE's pick for Supreme Court Chief Justice. A mixture of two opposite wings of the then Republican Party.
Reagan chose his major primary opponent George HW Bush as his veep even though Bush had just called Reaganomics "fuzzy math"
Biden chose Harris although she had just called Biden a racist who worked to maintain segregated schools. Reportedly Harris may be screaming at Biden in private conversations. But in public they seem like a happy team.
Democrat Tilden seemingly won the presidency beating Hayes, but a deal was struck allowing Hayes to be president in return for ending the military occupation of the South.
LBJ said it's better to have you enemies inside the tent pissing out, than outside pissing on your tent
reported by ABC's Sam Donaldson. LBJ seemed to refer to J.Edgar Hoover as FBI chief.
Woodrow Wilson had William Jenning Bryan as secretary of state, who eventually resigned in protest over Wilson's entry into WW2.
Republican Lincoln "the Great Emancipator," chose a Southern slave owner Democrat Andrew Johnson as his running mate in 1864. They won the election. But one got killed shortly thereafter and the other impeached, as well as a target of an assassination attempt. Sort of "winning the battle, but losing the war," although their side did just win the Civil War.
Every president got stuck with J. Edgar Hoover, as he had blackmail files on each president's private life and embarrassing information. See the movie "J. Edgar" Margaret Mitchel, AG's wife, said "when you've seen one FBI Director you've seen them all."
JFK had LBJ as veep, his major opponent in the Democrat presidential primaries. Stories were the Kennedys insulted LBJ, to the point LBJ is considered a prime suspect in JFK's assassination in "conspiracy" theories. RFK went after LBJ's close associates, prosecuting Bobby Baker and Billie Sol Estes, leaving an investigation that seemed to lead to an expected prosecution of LBJ himself. Same with J.Edgar Hoover. JFK reportedly planned to dump both LBJ as his veep in 1964 and fire J. Edgar. The animosity was so great, both were considered suspects in JFK's death and the alleged framing of Oswald.
