The Dems had an effort in about 5-6 known corrupt Dem cities, Detroit, Philly, Atlanta, cities in MI and Wisconsin and parts of Phoenix area and LV. Not sure if this was a scalable operation. Hopefully the purple Congressional districts in many places can still have some semblance of legality.
Their thievery was way more widespread than the few areas you mentioned.
This was industrial scale theft involving multiple levels of thievery.
