Illinois voters voted on several ballot measures in 1988.[4] In order to be approved, measures required either 60% support among those specifically voting on the measure or 50% support among all ballots cast in the elections.[4]

The Illinois Redemption Period for Tax Delinquent Property Amendment, a legislatively referred constitutional amendment which would amend Article IX, Section 8 of the Constitution of Illinois to modify the redemption period on the sale of a tax delinquent property, failed to meet either threshold to amend the constitution.[4][5] It only missed the threshold of 60% of votes cast specifically on the measure by a mere 0.87% margin (21,960 votes).[4][5]

Voters approved the Voting Requirement Amendment, a legislatively referred constitutional amendment which amended Article III, Section 1 of the Constitution of Illinois to lower the voting age in the state constitution to 18 and lower the residency requirement to vote to 30 days.[4][6]

A measure which would call for a state constitutional convention failed.[4][7] Article XIV of the Constitution of Illinois requires that Illinois voters be asked at least every 20 years if they desire a constitutional convention,[8][9] thus this election was an automatic ballot referral.[7] It was constitutionally required to be held, since the last vote on holding a constitutional convention had occurred in 1968.[7][8]
