Though passage has been in the balance all week, the vote against the bill was larger than many expected. When the final vote count was read, House Democrats cheered loudly, led by members of the Congressional Black Caucus who had fought the food stamp cuts.
The defeat is also a major victory for conservative taxpayer groups and environmental groups who have unsuccessfully worked against the bill for years. Those groups have aggressively lobbied lawmakers in recent weeks, hoping to capitalize on the more than 200 new members of the House since the last farm bill passed five years ago. Many of those new members are conservative Republicans who replaced moderate rural Democrats who had championed farm policy.
Those groups were emboldened after the vote.
"We need to put farm subsidies on a path to elimination and we need to devolve food stamps to the state level where they belong," said Chris Chocola, president of the conservative advocacy group Club for Growth.
