Illinois voters will decide whether the state will move to a progressive income tax model from a flat tax this November, and the advertising blitz is underway.

The group “Vote Yes for Fairness” and AARP have produced ads supporting the proposed constitutional amendment. One ad claims 97 percent of Illinoisans will pay the same or less in taxes, while people making above $250,000 will pay more. Another ad said a yes vote will raise taxes on the top 3 percent, generate almost $3 billion a year and protect your retirement income.
