This raises a question: Why are lawmakers so willing to vote for farm subsidies — even lawmakers who usually oppose government spending? …
One theory is that money explains it all. Wealthy agribusinesses are somehow paying off Republicans to vote their way. …
Not everyone’s convinced by this, though. In a recent working paper (pdf), Duke University economist Marc Bellemare and political scientist Nicholas Carnes came up with a better reason for Congress’s ag-subsidy love. Farmers and farm owners have disproportionate political sway in key districts. …
Bellemare tells me that he expected agribusiness lobbying to have the biggest impact on various farm votes before they did the study. But that wasn’t the case. Pressure at the polls turned out to be the key factor.
That’s Brad Plumer on the Washington Post‘s WonkBlog in a post about why Congress supports agriculture.
