States have select powers over the federal government that are specifically provided by our Constitution: https://en.m.wikipedia.org/wiki/States%27_rights. When you vote in local elections, you are in effect in control of certain outcomes within your state, as accorded by our Constitution.
The federal election determines representation for every single person in the United States and, in part, how federal governmental power is exercised on their behalf. There is no conceivable logical reason why citizens in any particular state should have more or less say in such matters than those in any other. The electoral college system is an absolute sham that deprives a significant number of people of their Constitutionally-guaranteed right to fair representation at the federal level.
I’d welcome any well-formed argument to the contrary. I’ve yet to ever hear one.
