>>>and to put the administration of federal elections in the hands of an independent, professional, non-partisan electoral commission.

Even if you have a federal electoral commission, the "foot soldiers" who will be working in the election booths will be the same people who is doing it now. (Based on what I know about the system in India, there it a election commission, who provides the administration and drafts Central/State government employees to carry out the elections). I agree that the net effect of such a measure will be positive, if there is more uniformity in the voting rules.
