I don’t remember any MedPage Today stories about the nurses who anonymously reported that they did not treat anyone who they knew was MAGA, or intentionally made injections and other procedures more painful for patients who they knew were MAGA. Those stories were in the conservative news during the last Trump term.
I don’t know any nurse who gives enough of a hoot to care about the politics of the people they are giving shots.
It is more likely the nurse just sucks at giving shots. Or the person getting the shot thinks too much of themselves.
99% of people providing services just want to do their job and go home.
