And if so, what are possible implications for such an outcome to happen? Will these parties gradually adopt ML reforms? Or will they revolutionise their countries into proper emancipated ones?
I'm curious about these two since they're the best organized parties inside the capitalist sphere.
Communist takeovers can only happen via revolution, bourgeois "democracy" won't ever allow it.
EFF is basically setting up for a collapse of the ANC government and either taking power electorally as the failing ANC capitulates to their popular front or by guiding the next crisis into a revolution.
The KPRF has no crisis to leverage for themselves as both URP and the KPRF are looking good for their support of the SMO. If the URP starts fucking up the SMO you can expect the KPRF to gain more traction especially in the new republics and the borderlands. I'm not kidding when I say that Russia could electorally come back into Socialism since it has such a weak bourgeoisie that's totally reliant on state intervention and the international trade system. Having already been a workers' state the nation has the muscle memory for it. They just need a vanguard to awaken it.
Putin has been arguably quite successful in restoring Russia from the brink of destruction, brought back some degree of prosperity, restored Russia's influence on the international stage (as far as the global south is concerned), and is successfully challenging western imperialism, so he will likely never lose an election. He is genuinely popular. But he is 70 years old. At some point he will retire or die and there is no other figure among the bourgeois parties with the same kind of popularity in Russia. At that point the political struggle will begin again in earnest and the KPRF will have a chance to make the argument that a return to socialism, perhaps in a form that takes inspiration from the proven success of the Chinese model, is the only way forward for Russia if it wants to continue to increase prosperity for the overwhelming majority of people and prevail in the struggle against imperialism.
That was the line I was thinking off, if putin actually does retire from politics (unlikely in this decade, but you never know) The KPRF have an actual chance of winning an election. And since the country's failure of capitalism, and the huge success under socialism, we might not see much opposition from them (I imagine the oligarchs, liberals, and priests would be opposed to it, but some of army officers who were under the USSR might actually support KPRF rise to power).
