Sorry, but that is laughable. If there was a presidential election in the US with two candidates, and after the election the governor of California installed Weird Al Yankovic instead of the elected candidate as the new presdient, would you call it democratic simply because the governor of California was elected?
If in the US instead of a president, all you could elect was party functionaries to an institution with the explicit purpose of being between the voters and the decision and they then voted somebody in as president against the popular vote, would you call that democratic?
Because that's what happened in 2016 and many times before that.
