Why is it rare to see John Adams and Thomas Jefferson in office together?

John Adams and Thomas Jefferson rarely served in office together primarily because their political ideologies diverged significantly over time, especially after the founding years of the United States. Adams was a Federalist, advocating for a strong central government, while Jefferson was a Democratic-Republican, promoting states' rights and agrarian interests. Their political rivalry became pronounced during the 1796 and 1800 elections, leading to the latter election being particularly contentious. Ultimately, their differing visions for the country kept them from holding office simultaneously after Adams' presidency ended in 1801.
