What is the minimum age to vote in Illinois?

The minimum age to vote in Illinois is indeed 18 years old, aligning with both state law and federal law under the 26th Amendment to the U.S. Constitution. This amendment guarantees that citizens who are 18 years of age or older cannot be denied the right to vote based on age. By establishing 18 as the voting age, Illinois ensures that all citizens who have reached adulthood and are eligible to participate in the democratic process have the opportunity to express their preferences at the polls. This standard reflects a national consensus and underscores the importance of youth engagement in civic matters.
