A major difference between Joseph Ellis's and John Meacham's historical interpretations of how Thomas Jefferson approved the Louisiana Purchase is discussed below.

For Joseph Ellis, President Jefferson acted beyond his executive powers to seal the deal for the land purchase of Louisiana from France. He noted that Jefferson reluctantly became an imperial president to make the US an empire today through the ambitious and arduous purchase of the Louisiana land. According to Ellis, this Jeffersonian move defied his 1800 presidential campaign promises to reduce federal power and debts and adhere strictly to the Constitution.

On the other hand, John Meacham, another presidential historian, praised Jefferson for this decisive acquisition. He noted that despite Jefferson's penchant for avoiding controversies, he behaved like the true philosopher and politician by applying his thinking and maneuvering skills to buy the land at a not-too princely bargain of $15 million.

Thus, Ellis's interpretation looked at the constitutionality of Thomas Jefferson's Louisiana Purchase against his campaign promises, while Meacham's interpretation praised Jefferson for acting beyond his character to make decisions in the best interest of the US.
