Answer:
Step-by-step explanation:
The author of Brutus 1 was most concerned about the feature of the United States Constitution that gave the federal government too much power at the expense of the states. Specifically, they were worried about the Supremacy Clause, which stated that federal laws and the Constitution itself were the supreme law of the land, effectively placing the federal government above the individual states. The author believed that this would lead to a consolidation of power in the hands of the federal government and a loss of liberty for the people.
