Andrei Zhdanov was the expected sucessor of Josef Stalin, but he died years before his master due his extreme alcoholism and became a historical footnote.
By having the (improbably) PoD of him controlling his drinking (near ASB, but there is no history otherwise), and having Stalin to die on a more "controlled" way through the spam of months, allowing him to announce Zhdanov as his sucessor, purge the people who oppose him, and introduce Zhdanov to the soviet media as the best possible candidate, how would Zhdanov government be?
