The electors are absolutely bound by their actions.

Whatever laws Congress may pass, the people must strictly obey; thus the servants of the people really become their masters.

There is no fear, however, that their masters pro tempore will betray their trust, as any neglect of duty on their part, or disregard of the wishes of their constituents, would most likely destroy their chances of re-election.
According to the terms of the Constitution, the senators and representatives must be residents of the states for which they are chosen.

This is an excellent provision, insuring that the people's delegates possess local knowledge and know how to safeguard the interests and welfare of the states which sent them to Washington.

On the other hand, as each state, irrespective of its size, is entitled to elect only two Senators, and to send only a limited number of Representatives to the House, proportionally to its population, unfortunately it frequently happens that eminent, capable, and well-known public men, of large experience, are deprived of an opportunity to serve their country.
