Woodrow Wilson was one
William Henry Harrison and James Garfield both died before they finished one year as President.
John Adams is one of them.
no one knows
One. FDR.
There was only one in the US- Woodrow Wilson (Some might say that Mrs. Wilson also served as President after Woodrow had his stroke.)
find a counterexample to the statement all us presidents have served only one term to show statement is false
There were 40 presidents from 1789 to 1990. (Grover Cleveland served twice, I count him one; counting this way, George Bush was the 40th, who had started his term 1989.)
George Washington is the president that appointed the most Supreme Court Justices. There have been only seven US Presidents that served only one term.
There are 2 US presidents who served less than one year in office. William Henry Harrison died after serving only one month in office, and James Garfield was shot and killed after a total of 200 days in office.
No one has and no one ever will because Presidents are capped at 2 terms now, which is 8 years
