Farm bill politics
It takes a minimum of 218 votes for a bill to pass the U.S. House of Representatives, and an analysis of the nation’s major crop-growing regions demonstrates that compiling those votes requires compromise among the various commodity interests.
Out of the 435 congressional districts:
82 intersect the 533 major US corn-producing counties
38 intersect the 148 major US cotton-producing counties
98 intersect the 495 major US spring/winter wheat-producing counties
