This is going to be a multi-question post.
Trotsky was laid low by sickness at inopportune times during 1923-24, around Lenin's death, when he would emerge as leader of the Left Opposition.
WI Trotsky had died from sickness around this time?
What happens with the Soviet succession struggle with both Lenin and Trotsky dying (from natural causes) around the same time?
Does the Bolshevik Left Opposition still form? If so, who leads it? Will they be as iconic as Trotsky and be able to articulate/propagandize their own ideological current like OTL Trotskyism? Or will the Left Opposition dissolve and fade away from the history books like the Right Opposition did? (I can't really see any leading Left Oppositionists (e.g. Radek, Rakovsky, Bubnov, etc.) being able to effectively lead the movement or produce as much popular writing as Trotsky did abroad, so I think it will be crushed and forgotten much earlier).
Also, with Trotsky conveniently gone, does Stalin break with the troika (Zinoviev/Kamenev) and/or the Right Opposition (Bukharin/Rykov/Tomsky) much earlier to seize absolute power more quickly? Or does he still follow largely the same path to power as IOTL?
Lastly, if nobody takes up the mantle of Trotskyism, who becomes the primary "wrecker" scapegoat for the Stalinists?
