Grampa Bernie visited South America in 1985 and advised the revolutionaries on methods of bunking America via the airwaves. A very disloyal act. Equivilent to you conducting a sympathetic hello visit to Iran today.
This is a VERY instructive video about what and who we are dealing with. He sounds soooo reasonable with his defective behavior.
Unfortunately unless you were around in those days or are willing to do your due diligence research on Nicaragua and their Cuban led communist revolution...who were enemies to the U.S. at the time you can't understand how heinous this guy was...and is.
As Grampa Bernie allows...he has always had a fascination with SA...and communism.
