Final answer:
The Illinois Constitution mandates that voters must fulfill residence, age, and voter registration requirements to be eligible to vote.
Step-by-step explanation:
The three specific requirements found in the Illinois Constitution for the right to vote are residence, age, and voter registration. To elaborate, individuals must be residents of the state for a specified period, typically thirty days. Secondly, potential voters must be at least 18 years of age by the time of the next election. Lastly, they must successfully complete the process of voter registration, which may include providing a government-issued identification and confirming competency to vote. Felony convictions can affect eligibility, with each state having its own laws regarding felons and voting rights.
