Commissars (the political office) and Cheka officials had similar numbers in terms of representation.
Underlying reason included the suspicion that anyone Orthodox was tainted by secret sympathy for the Tsar or the Orthodox church.
Jews were therefore seen as trustworthy, having no alliance or sympathy for the Tsar, or for the Orthodox beliefs.

The first Politburo was:
Lenin (his mother's father was jewish. Judaism is transmitted maternally, so neither of Lenin's parents were jewish, and neither was he)
Trotsky: jewish
Stalin: Not jewish. Launched Anti-semitic campaign around '50
Lev Kamelev: Jewish father, orthodox mother -> not jewish (see above)
Nikolay Krestinsky Not jewish
So that's 1/5, or 20%, and you're an anti-semitic troll with no interest in the facts.
You are also ignoring the part where the only Jew in the Politbro was executed rather early, while a member with absolutely no connection to Judaism, namely Stalin, appears to have had a rather, let’s say, “outsized” influence on the later failings of the system you want to nstrumentalize in your anti-Semitic insinuations.
Not to mention that this summation of individual sins and good deeds in an effort to paint their associated groups is the very definition of prejudice. In fact, I now realize I should probably never have bought into that premise?
(also: If you start arguing Lenin's judaism based on his heredity, I will invariably have to violate Godwin's law)
