create a rule that all Congresspeople while in session must wear jackets bearing the names of their major contributors

This is advocating that we know who has paid for the campaigns of our congresspeople. Much as race car drivers and cyclists, and other figures, display their sponsors on their clothing, so our Congress should have to display their sponsors for all to see. Just the major sponsors (perhaps those contributing over $10K). Basically it would be a patch jacket provided to each member (no need to deface their nice Armani suits).
