um... sure
Poor reasoning on the part of the blog author. A majority of the waiver denials were unions — that doesn’t disprove union favoritism; we don’t know the number of people covered by those plans, and we can’t compare that to the number of unions getting waivers.
We don’t know how many unfavored groups are not even bothering to ask for waivers. We don’t know if the unions are being coached on how to file requests that meet the criteria they claim to be using.
