Winthrop argued that because the states are so dissimilar, they must be free to for themselves. One major concern of Antifederalists such as Winthrop was that the proposed Constitution’s clause gave too much power to Congress. Which of these statements captures an objection Winthrop had to the proposed Constitution? a. It made congressional laws the supreme laws of the land. b. It took too much power from Congress, giving it to the president. c. It forced states to abandon standing trade agreements with other states.

Winthrop argument was what was stated in the sixth article of the Constitution as at the time; which ensured that the continental laws shall become "the supreme law of the land", ensuring that every judge regardless of the state is bound by these laws, notwithstanding whatever the laws of the state is. Winthrop argued that making congressional or continental laws the supreme laws of the land was not right because every state has its own characteristic and must be allowed to create its own laws.
