In general, the other Republican leaders believed that since treaties to buy and sell land were then common, and since Article II didn’t specify some specific type of treaty that the president could make with the advice and consent of the Senate, the president could constitutionally make treaties to buy and sell territory. So far as I know, Jefferson was the only significant Republican who wasn’t persuaded by this argument.
By the way, John Taylor apparently apparently didn’t write A Defense of the Measures of the Administration of Thomas Jefferson. For more on that, see the Appendix to Shalhope’s Taylor biography.
