MADISON, Wis. (AP) – A Wisconsin Assembly committee has approved a bill that would limit the amount of food stamp benefits that could be spent on junk food.  Republican Rep. Dean Kaufert, of Neenah, has amended his original bill to require people enrolled in the state nutrition assistance program, known as food stamps, to spend at least two-thirds of their monthly benefits on items such as milk, bread and vegetables. They could spend their remaining benefits on any authorized food.  Kaufert’s original bill didn’t specify an amount to be spent on whole foods.  Kaufert says he wants people to eat healthier, but Democrats on the committee say he’s just trying to score political points.  The measure passed 7-2 Tuesday on a party line vote. The full Assembly will take it up in May.
