The fight over a progressive income tax is underway and Senate Republicans are trying to make it harder for income taxes to be raised in Illinois. 

They want a two-thirds majority to be required to pass any law that bumps up tax rates or increases fees. Republican Dan McConchie says they want to find a way to hold the line on proposed hikes to taxes and fees.

The bill looks likely to go nowhere – three-fifths of lawmakers will have to approve the proposed amendment.
