The poltical parties to which America's presidents have belonged while
holding the office of the Presidency of the United States (POTUS). The party
party affiliation of some presidents changed while they were in office, e.g.,
Abraham Lincoln
was a Republican when he was first elected to office, but ran under the
National Union Party ticket when he sought re-election in 1864 during the
Civil War—that party name was used to attract Democratic and
Unionist
Party members who did not want to vote for a
Republican Party candidate.
John Tyler was a Whig
when he became president in 1841 at the death of President William Henry
Harrison, who died in office one month taking the oath of office, but he
was expelled by the party that same year after disagreements with the party's
leadership.
