I don't know if I have the time to explain how the democratic party has shifted its solidification of primary power since that time, largely because of outside runs like Obama and more specifically Sanders. Or the difference in running a second presidential run directly after a failed campaign compared to running after serving as VP.
This is not a gotcha or some kind of flaw in my reasoning. Ultimately it doesn't fucking matter because working people will not see substantial change through electoral politics.
Edit: also I'm going to add you should just state your point in your first reply instead of trying to bait out people your conversing with a stupid question. It is much more respectful of peoples time and effort.
