What is the salary of an elector?
Is it different from state to state?
What are the qualifications to be one?
qualifications none but he’s black so it’s ok for the msm.
It is not a full-time job. You only have one duty, to cast your ballot on the prescribed date. I expect the salary is zero and there might be a one-time small stipend.
There are no qualifications as required by the Constitution.
Rabid party partisans are selected to ensure that they vote for the candidate the state selected. States try to enforce their vote but the Constitution allows them to vote for anyone.
