They also pull out this trick in reverse to defend vile centrists like Neera Tanden where they use her identity and record of having received federal benefits to pose her as someone that would defend them rather than someone dedicated to destroying those programs, who attacked an employee, who outed an employee who was sexually assaulted, and suggested stealing Libya's oil to pay for bombing them.
She might not be getting her nomination, but it's a great example of the tactic in action.
Tanden is notable only for her poor social media discipline. There are a hundred less progressive officials in the new administration, who happen to be circumspect enough to take money from Middle Eastern dictators without rivaling Trump in Twitter foolishness.
What "ThinkProgress" do you mean? This one [0], at which the most recent article is from September 2019? That was indeed a union shop, which was cited by Tanden in an internal email as the reason she closed it down. [1] Maybe we should credit her for not calling in Pinkerton assassins, but closing down a workplace because of its union is precisely "union busting".
