Should food stamps be harder to get?  Some conservative members of the Unites States House believe say yes.  That's why they're supporting cuts to a wide-ranging farm bill that would cut food stamps by two billion dollars a year, and make it more difficult for some people to qualify for the domestic food aid program.  The proposed cuts are three percent of the food stamp program, now called the Supplemental Nutrition Assistance Program.  Passage of the five-year, half-trillion-dollar farm bill could depend on the level of cuts to the $80 billion dollars a year program.  Many house conservatives have said the cuts don't go far enough, while liberals have argued against the cuts.  The House is expected to begin voting on 103 amendments to the farm legislation today.
