In 1787 delegates of the 13 American colonies met in Philadelphia and wrote a new constitution.
The primary issue of contention in creating this document was the representation of the large states and the small states in the new government.
The small states were opposed to a Congress and president selected strictly on the basis of the popular vote.
The compromise reached on this issue allowed for a House of Representatives elected on the basis of population and a Senate with two members from each state.
The president would be chosen by electors from each state.
The number of electors was the sum of the number of representatives and the number of senators.
The electoral system thus gives a slight advantage to small states.
The proposal to start electing the president based only on the popular vote would sacrifice that advantage, so that large states like New York and California would have more impact in a presidential election.
Small states like Louisiana would see their already minor influence diminished.
Unless you favor letting the larger states in the country control the selection of the president, switching to a process based on the popular vote is a losing proposition for Louisiana.
