Her longest collaborative relationship is with Peter B. Collins who is undoubtedly a progressive. And I don't think she would have much in common with libertarian think-tank supporters like the Koch Brothers.
She seems to be first and foremost supportive of critics of the national security state, so mainstream Democrats and Republicans will not be her cup of tea. She does not personally speak much about economics or neoliberalism and such, so it is not really honest to try and ascribe to her a whole collection of views that she does not regularly espouse.
On her radio show with Pert B. Collins, she has interviewed more people from the Left side of the spectrum than from the libertarian right, e.g. Peter Phillips, Russ Baker, Nafeez Ahmed, etc. She also interviewed Lew Rockwell so obviously I cannot claim that she is a full-on progressive. I personally think that she is not very knowledgeable about political economy so she doesn't take any doctrinaire positions on these issues. For example, if she studied a little bit, she could easily formulate a critique of neoliberalism that jives with what she knows about the dark side of the national security state. After all, neoliberalism as we know it was first instituted in Chile thanks to a CIA coup. And yes, neoliberalism with its privatization and deregulation is but a tiny bit away from libertarianism.
I have read her book and I recommend it. She is very smart and courageous.
