1. Republicans control all three branches of government.
  2. Thus, pork goes disproportionately to Republican congressional districts.
  3. Republican congressional districts tend to be either rural or exurban.
  4. Rural pork is composed primarily of agricultural subsidies and exurban pork is generally car-friendly.
  5. Agricultural subsidies and car-friendly infrastructure development are environmentally destructive.

Whatever to do?
