Speaking of lawyers, there is a VERY wealthy one in Houston who supports a large number of leftist causes with the Democrats. Can't remember his name. Another Oligarch is Warren Buffet. Another is George Soros who is a citizen of another country, but still exerts tremendous influence here with his filthy money. Some of them live in Mexico and exert influence here (Carlos Slim Helu). If you're not getting the picture, then you don't WANT to. Many of them are extremely private and hide behind the people they support.
Look up this guy: Peter Denis Sutherland on wikipedia.
