I have no love for McCain but don’t begrudge him his cancer treatment provided by his work related insurance policy.
At 80 the VA told my father “you’re too old for us to try to cure your prostrate cancer”.
Thankfully his wife’s retirement insurance helped him find a doc who kicked the cancer’s butt.
Far too many veteran’s don’t have that extra layer of insurance. My dad got lucky (and is super healthy today). McCain is one of the lucky ones.
