MADISON, Wis. (AP) – The Wisconsin Assembly has approved a bill that would limit the amount of food stamp benefits that could be spent on junk food.  The bill, authored by Republican Rep. Dean Kaufert of Neenah, would require people enrolled in the state’s food stamps program to spend at least two-thirds of their monthly benefits on designated items such as milk, bread and vegetables. They could spend their remaining benefits on any authorized food.  Kaufert says recipients should use taxpayer-funded food stamps responsibly to eat healthy. But Democrats argue it may be difficult and expensive to implement new rules and the proposal will not help create jobs.  The measure cleared the Assembly on a 68-26 vote Tuesday. It now heads to the Senate.
