WASHINGTON — Farm-state lawmakers hoping for passage of a farm bill by the end of the year will have to bridge a deep divide between the House and the Senate over the role of the government in helping the nation’s poor.

The House passed a bill Thursday that would make around $4 billion in cuts annually to the almost $80 billion-a-year food stamp program and allow states to put in place broad new work requirements for recipients. A Senate-passed farm bill would make around a tenth of the amount of those cuts, or $400 million a year.

“This bill is designed to give people a hand when they need it most,” Majority Leader Eric Cantor, R-Va., said on the House floor just before lawmakers passed the bill.

U.S. Rep. Mike Kelly, R-3rd, voted in favor of the bill.

The White House threatened a veto, and Senate Democrats angrily criticized the level of cuts.

“The Senate will never pass such hateful, punitive legislation,” said Senate Majority Leader Harry Reid, D-Nev.

For decades, Congress has combined farm programs with food stamps to garner urban votes for the rural measure. But food stamps have complicated the process this year as House conservatives have called for cuts. The cost of the food stamp program, now called the Supplemental Nutrition Assistance Program, or SNAP, has more than doubled since the Great Recession deepened in 2008. More than 47 million Americans, or 1 in 7, are using the program.

The Senate passed a bill including both food stamps and farm programs in June. Later that month, the House defeated a farm bill that included both the food and farm programs after conservatives said its food stamp cuts — around $2 billion a year — weren’t high enough.

GOP leaders then split the farm programs from the food stamps and passed a farm-only bill in July. Conservatives crafted the food stamp bill, saying higher cuts would be easier to pass in a stand-alone bill.

Getting the three bills into a House-Senate conference could be tricky under House rules. Republicans said Thursday that one more step is needed — the House will have to hold a procedural vote to allow both the farm and food stamp bills to go to conference.
