WASHINGTON — The last time Congress passed a farm bill, Democrats had control of the House and the food stamp program was about half the size it is today.

That was five years ago.

Conservatives calling for an overhaul of the domestic food aid program will try to trim the nation’s nearly $80 billion grocery bill when the House weighs in on farm legislation in a few weeks. The Senate overwhelmingly voted Monday to expand farm subsidies and make small cuts to food stamps in a five-year, half-trillion dollar measure. But passage in the House isn’t expected to be so easy — or so bipartisan.

House Speaker John Boehner, R-Ohio, said Monday that his chamber will take up its version of the farm bill later this month. He made clear his own dislike for generous farm subsidies included in the bill, saying his “concerns about our country’s farm programs are well-known.” But Boehner acknowledged that the rest of the chamber might not agree with him.

“If you have ideas on how to make the bill better, bring them forward,” Boehner said in a statement directed to his colleagues. “Let’s have the debate, and let’s vote on them.”

House consideration will come after more than a year’s delay. The Senate passed a similar version of its farm bill last year, but the House declined to take it up during an election year amid conflict over the amount to cut from food stamps, now known as the Supplemental Nutrition Assistance Program, or SNAP. One in seven Americans now use the program.

The Senate bill would cut the food stamp program, now known as the Supplemental Nutrition Assistance Program, or SNAP, by about $400 million a year, or half a percent, and Senate Democrats have been reluctant to cut more. The farm bill approved by the House Agriculture Committee last month would cut the program by $2 billion a year, or a little more than 3 percent, and make it more difficult for some people to qualify.

In his statement Monday, Boehner signaled support for the House bill’s level of food stamp cuts, saying they are changes that “both parties know are necessary.” Other Republicans are expected to offer amendments to expand the cuts, setting up a potentially even more difficult resolution with the Senate version. Democrats are expected to try and eliminate the cuts.

Food stamps were added to the farm bill decades ago to gain urban votes for the rural measure, which sets policy for farm subsidies, programs to protect environmentally sensitive land and other rural development projects. But with the program’s exponential growth during the recent economic downturn, food stamps are now making passage harder.
