Joe has no one to blame but himself for his alleged hellish' life.
Joe probably viewed Juan as a war hero and a few other things. One’s view based on the media and what one might learn up close and personal can be very different. Spin all you want, but you and I also do not know, based on what we see in the media, prominent politicians as they really are.
The spin machine is always going around politicians and they all project a cultivated public persona. There have been many stories about the real McCain over the years, and his ‘charming’ personality.
