I suspect this is probably more complicated. My family members who live in small towns and rural areas have been having larger health issues and more trouble getting care even if they want to for years if not decades compared to my relatives who live in major urban areas, and particularly those who live in more affluent areas. Like I'd go so far as to estimate that affluent areas metro adjacent are +7 years vs. non-affluent metro areas, which are also like +7 years vs. rural/small town areas or slum/poor metro areas. But I also think the kind of care and non-care my relatives in smaller/rural areas leads to exhaustion, loss of faith in the system, and interest in alternative options.
But I also don't doubt that adding the modern conservative delusions and paranoia on top of it all only worsens everything.
Why would that make you more conservative? Republicans don't have any answers to fix the US healthcare system. It would be far more plausible that someone that experienced the failure of the health care system would vote for a populist position here, and for healthcare the more convincing populist position is certainly the left one.
That's misunderstanding the paper. The correlation here is with outcomes, not support. Republicans may very well be more "jaded" with the healthcare system. But that doesn't explain why they die early.
Through what mechanism does dissatisfaction with our for-profit healthcare system lead to support for eg. expansionist foreign wars or aggressive policing policies?
Well, Republicans, FAFO.
But I also don't doubt that adding the modern conservative delusions and paranoia on top of it all only worsens everything.
It is important to point out though, that the last opportunity to establish single-payer healthcare in the US was prevented by the democratic party.
The famous Hillary quote: "Single payer is off the table"
This is why the RNC has hated the Clintons, and especially Hillary, so much: they were muscling in on republican turf.
This because extreme over COVID. A particular low point was Herman Cain's Twitter account doing COVID denial while, and after, the man died of COVID.
