Nonsense it has no effect on federalism.
Federalism only works well when the States have the power to limit the central government.
Senators appointed by, and responsible to the State Governors and legislatures were the method our founders chose to do that.
The 17th amendment abolished that power of the states and established no replacement, and ever since the limited relatively weak Federal Government the founders envisioned has metastasized out of control.
