1 member of the United States National Republican Party has governed for a total of 4 years:

- John Tyler (1841–1845)[n 3]
The National Union Party was the name used by the Republican Party for the national ticket in the 1864 presidential election. Both Abraham Lincoln and Andrew Johnson associated with the National Union Party during the 1864 election and Andrew Johnson remained a member until he joined the Democratic Party at the end of his second term. Lincoln and Johnson served as President while members of the National Union party for 4 years.
- John Adams (1797–1801) was the first president elected as a member of the United States Federalist Party.
- Lincoln served his first term (from 1861–1865) as a member of the Republican Party, but ran for his second term as a member of the National Union Party and served only a short part of his second term in 1865 before being assassinated.
- Andrew Johnson did not identify with the two main parties of Democrats and Republicans, though he did try for the Democratic nomination in 1868, and so while President he attempted to build a party of loyalists under the National Union label. Asked in 1868 why he did not become a Democrat, he said, "It is true I am asked why don't I join the Democratic Party. Why don't they join me ... if I have administered the office of president so well?" This failure to build a new National Union Party made Johnson effectively an independent.
- Although John Tyler was elected vice president on the Whig ticket, his policies soon proved to be opposed to most of the Whig agenda, and he was expelled from the party in 1841, a few months after taking office as President.
