Can you imagine how much she and her ilk would freak out if candidates that appeal to people to whose votes they believe they are entitled actually ran in another party's primary? If lefty candidates decided they were done with Dems and tried something else? They would lose it.
Again, irrespective of your personal political philosophy, you cannot run the Democratic Party in this way. It works for Republicans because the conservative mindset values blind obedience. Literally every data point you have says that likely Democratic voters hate being managed like this.
