Corbyn, as Trump said of Robert de Niro, is a pretty low I.Q. individual; his first wife, Jane Chapman, said that she never knew him read a book in 4 years of marriage. Despite having all the advantages of educated parents and private and grammar schools, he managed just 2 E's at A-level and dropped out of the old North London Polytechnic, - which was not an institution famed for its intellectual rigour, to put it mildly.
'His [Corbyn's] academic failure was the midwife of his political failure. "Anti-Semitism is the socialism of fools", said August Bebel. Instead of seeing the power structure as it is and trying to change it, the anti -Semite fantasises about a cabal of Jews controlling everything'.
