The McStain lives on.
Sen. John McCain was consistent, at least in his actions, in his refusal to allow any further attempts to discover and recover missing American POWs in Vietnam as well as even the possibility of allowing any further investigation as to the possibility that Americans were still being held captive.
This is, of course, despite McCains incessant reliance on his military service as some type of qualification for whatever his political position of the day might be.
