Seems so
Well, he made it through that 2010 primary.
Hard to imagine a repeat in 2016
During the 2010 campaign, he intimated this would be his last term. However, he has since indicated that he just might want to run again.
I'm of the mind that he actually hoped to retire around 2014...and arrange to have his daughter, Megan the Insufferable, appointed to serve the balance of his term -- jump-starting her own career in the Senate's "McCain seat".
This country is not safe until McCain is padlocked in his Sedona home, tended to by caregivers.
