Many people, on studying the matter, have come to the same conclusion.
Gove (1894):
Another serious objection is that a heavy additional burden is imposed on the voter by requiring him to indicate several names in the order of his preference instead of indicating but one choice, as in the other systems. This burden the voter would be very loth to assume, since it is with difficulty that voters are induced to discharge the duties already imposed upon them.
Lien (1925):
While the Hare system is meticulously more accurate as a plan of proportional representation than the Free List system so widely used on the continent of Europe, it is certain that for the election of members of our state legislatures or of our Congress, the Free List plan (with its close approximation to complete proportional representation) would be much more in accord with our voting habits and consequently much more acceptable and intelligible to the voters.
Weeks (1937):
All states except Alabama and Oklahoma did not require the voter to register more than a first choice for any office. It seems to have been quite common in all the states indicated above that a great many voters failed to avail themselves of the privilege of registering second or more choices, which resulted in the practical restoration of the plurality system in many primary races. This failure was due to several causes: ignorance of the voter; his desire not to have his vote counted for any but his first choice; or his refusal to accept what was thought to be a complicated system, which, it was felt, could be easily corrupted or readily subject to mistakes in the count, or which seemed to provide for an unfair method of evaluating choices.
Gosnell (1939):
Under the list plan, the voters would have to choose only one candidate, the best man from the group which they favored most. The results of the election would be known shortly after the single-preference votes had been counted. It is urged that the proposed system would probably lessen constitutional difficulties, simplify the task of the voter, save the expense and delay of the Hare count, and give substantially the same results.
