Newt Gingrich Reveals: The Reason Why The Republican Party Is Attacking Donald Trump Because He Has Not Gone Through Certain Initiation Rites And Is Not A Member Of The Secret Society
Gingrich was referring to Trump not being “in the club”, the Foggy Bottom good ole boys network, the backscratchers, the wheelers and dealers. That dirty club where when you get there, no matter how “poor” you may have been when you set foot in DC, you seem to come out richer and smellier.
He probably was being metaphorical, but the fact is there are indeed secret societies with initiation rites belonged to by the movers and shakers. Try to get some information about Skull and Bones from George W Bush.
