Voter suppression will suppress the vote of targeted voters, enabling desired people to win unfairly.
Explanation:
Voter suppression is not the act of suppressing votes but suppressing <em>certain</em> votes in order to reach a favorable outcome (for those wanting the suppressing.) This puts the strength of U.S. democracy in a critical position: Democracy is all about choosing who rules over them, or, more accurately, serves them. Voices contrary to the suppressor's is the exact opposite of that. This can result in unfair elections that will allow certain people to take power when they aren't who voters want.
