Some state lawmakers are proposing new work requirements for people receiving food stamps under the Supplemental Nutrition Assistance Program, known as SNAP, and for people receiving government-subsidized health insurance under Medicaid. Others want welfare recipients to pass drug tests. Many are looking to crack down on fraud by requiring recipients to prove their eligibility more frequently and with better documentation. Efforts to ban the purchase of junk food and soda with food stamps are also ongoing. In Wisconsin, Republican Gov. Scott Walker last week called a special session for lawmakers to consider a package of draft legislation that would impose more restrictions on food stamps and Medicaid. His proposal and many others are driven by the philosophy that government benefits should only be temporary, and that people should earn the benefits if they can.But Democratic leaders and welfare advocates say the restrictions Walker and others are pushing would strip people of the support that is allowing them to scrape by, and drive them deeper into poverty.
