there was the 'goat gland doctor'. [en.wikipedia.org]
Operating from a small clinic in Milford, Kansas with a medical degree from a diploma mill he achieved national fame and soon started his own radio station. Eventually the AMA convinced the State of Kansas to revoke his medical licence, so he ran for Governor and almost won! Unable to appoint his own State Medical Board, he moved to Del Rio, Texas and built a new powerful radio transmitter across the river in Mexico. Eventually lawsuits drove him into bankruptcy.
