Agnew was so corrupt that he was still accepting cash every month in a manila envelope for some corrupt deal he had made when he was governor of Maryland. He was never very smart.
The dirty little secret about Agnew was that what he did was typical of most governors in the country—and btw still is today.
My grandfather owned a construction company and got state contracts in another state (CT) by giving briefcases of cash to the governor and other leading politicians.
They actually met for the payoffs at a hot-dog stand twenty miles away from Hartford.
My grandfather was trying to recruit me for the business and took me to the hot-dog stand so I would know where to make the payoffs.
As soon as I got finished with my formal education I fled to the opposite coast!
