Please help me with this question:

"The proposed Constitution, so far from implying an abolition of the State governments, makes them constituent parts of the national sovereignty, by allowing them a direct representation in the Senate, and leaves in their possession certain exclusive and very important portions of sovereign power. This fully corresponds...With the idea of a federal government."

-Alexander Hamilton

How does Hamilton assure that the new government is no threat to the individual State governments?

(Real answers onle please!!!) :) Thank you
