Answer:
D) Voters in states with late elections had less power over the outcome of elections than voters in states with earlier elections.
Explanation:
According to the statements from the text, it was noted that states were allowed to hold elections within a 34 day period before the first Wednesday in December but it had a big flaw.
The flaw was that early voting results could affect both the turnout and opinion of the other late voters, which in turn could affect the overall outcome.
Based on this evidence, one of the "crucial flaws" in the voting system before then was that Voters in states with late elections had less power over the outcome of elections than voters in states with earlier elections.
