Vance: ‘Laura Loomer is not affiliated with the Trump campaign’

Let's assume that she isn't, being generous and disregarding OP's photos for a moment.

If both Trump and Vance are echoing this "pet-eating" stuff that she has said, it doesn't really matter whether she's affiliated or not, does it? The campaign is about putting two people -- Trump and Vance -- in office. Any formal affiliation that Loomer has is only meaningful insofar as it affects what Trump or Vance (or, I guess, the Trump-Vance campaign) is doing. And it really does seem that what she's doing is affecting all three. Or that she's drawing from campaign planners via a backchannel, which is again functionally equivalent to being formally-affiliated with the campaign in terms of what anyone would care about.
