According to George Mason, why would the new constitution protect the rights of Americans better than the various state declarations of right ?

For him, the constitution would establish equality between citizens of each state, putting an end to state governments that did not establish equality between citizens of different states.

Explanation:

George Mason wrote Proposed Federal Constitution: Addressed to the Citizens of Virginia in 1787, where he testified in favor of the creation of a federal constitution as he believed that such a constitution would be essential to protecting and promoting the rights of all citizens equally. This is because, for him, the constitution would terminate the state governments and this would be beneficial, because the student governments created several declarations of rights that created differences between citizens of different states. By creating only one bill of rights through the federal constitution, the government would establish equality for all citizens.
