As somebody privately noted to me: Janet Napolitano is undoubtedly resigning from DHS in order to have a clear run for McCain’s Senate seat. And I for one am opposed to John McCain remaining a Senator past this term. Not enough to simply let Napolitano have the seat; but there are people out there who are much less loyal to the GOP than I am, and many of them live in Arizona.
John McCain will be 80 in 2016. His health has not been good for pretty much my entire lifespan*. It is time for him to retire.
*For entirely honorable reasons; the man is a torture survivor.
