Do you know of a good source that explains this dynamic a bit more clearly for the uninitiated? I'd be interested to understand the details a bit better.

Maybe not what you had in mind, but I think the boom and bust cycle for MCOs and varying risk management policy responses by different states (risk corridors etc.) are super interesting. KFF did a good explainer www.kff.org/medicaid/iss...

I feel like I'm being trolled, either by Kessler, Hobbes, or both, but in any case the end result is that we are all more aware of the context for Harris's attacks than if Kessler hadn't written the fact-checker.

I don't understand the complaint here? Kessler is amplifying and refining Harris's (valid) attacks. No one is reading these and concluding that Harris is a liar -- they are just learning more about the facts behind her claims, with regard to important topics. Isn't that a good public service?
