It seems the Democrats have gone nuclear on the communism/socialism thing: they arranged an election where their candidate was selected by the Democratic Party oligarchs, not by the people. By having Biden drop out after the primary, they made it necessary for the DNC to select an nominee without the help of the voice of the people. Events at this level never happen by accident; they planned it to happen this way. Probably Obama planned it this way.
The DNC made it worse by specifying that no delegate to the convention could vote for anyone other than the selected nominee, oligarch-style, to ensure that their chosen nominee won the "vote."
It astounds me when the Democrats made such a fuss about Trump being the thrall of Russia (made up, of course), that they then duplicate the Russian voting system. That system is a revitalized communist plan, run now by Putin and his oligarchs.
I've used this image before, but it's still appropriate. The Democratic National Committee's version of the future:

Communism today is alive and well in the United States and flourishing in the Democratic Party.
