The
Congress may determine the Time of chusing the Electors, and the Day on which they shall
give their Votes; which Day shall be the same throughout the United States.
It’s pretty straightforward. The “chusing the Electors” is what you are doing when you vote for
president and vice-president of the United States.
The constitution grants Congress the explicit power to
determine the time of the election for president and vice-president and
requires it must be the same throughout the United States. So early voting
fails on two counts:
1. States
are usurping the authority of Congress to determine the day of the election by
holding early voting.
2. Early
voting days are not uniformed throughout the United States.
In off-year elections states have pretty much to power to
hold elections as they see fit. The constitution is silent on elections for
every other office. However, as long as president and vice-president is on
ballot, there can only be one election day throughout the United States as
designated by Congress.
