It's the use of "rigged" that throws me. I agree money in politics is bad, and adds improper influence and incentive into the whole thing. That is not the same context that we have widely seen "rigged" used in the last 8 years. The term brings to mind GOP lies about election integrity, and bogus claims of fraud.
If this was just someone I was talking to I would brush the statement off as bad word choice, and move on if there was nothing else. With it being a statement after an election loss from someone with political experience I struggle to let it slide. Word choice and presenting ideas/policy is a major part of the job she is running for, and I think such poor word choice in a statement she had every opportunity to proofread and consider is worthy of some criticism. Doesn't make her an election denier, or anything of the sort, but it does warrant a little slap on the wrist from the public.
Overall she's right, but there were many better ways to say it.
I work for a neurologist practice, and the amount I have to argue with insurance (and inevitably have to get the neurologist on the phone to directly request something for many) is insane. A good chunk of my job isn't providing care, but arguing with insurance that the care is necessary. These companies are actively delaying patient care, and try to blame the physician whenever possible.
Wildly infuriating, especially when the denials are worded along the lines of "we reviewed this, and don't consider it medically necessary". Motherfucker, a doctor said it was necessary and listed the clinical reasons why this test or procedure would be beneficial. Nothing has radicalized me for universal healthcare more than working in healthcare.
