So it’s perfectly constitutional for a state not to have an election for President, but rather have the electors chosen by the state legislature.
With all due respect quietly desperate, the Constitution clearly says nothing about the states having a popular vote for a president. I think that you may be overlooking the federal government’s constitutionally limited powers.
Again, one of the very few constitutionally authorized domestic federal spending programs that probably most citizens regularly use is the US Mail Service. And I would guess that ordinary citizens would lose interest in the POTUS if having problems with the US Mail Service was the main thing that they might discuss with the president.
Other things that citizens might discuss with the POTUS are trade issues, treaties and military issues.
Note that the only federal entity that the Founding States gave ordinary citizens the power to vote for is members of the House of Representatives (HoR), not federal senators, the POTUS or Supreme Court justices. This is because the HoR is the only federal entity the Founding States authoritized to initiate tax appropriations bills (1.7.1).
