I will never vote for Mitt but this story is pure bull.
To "hang it around his neck" has nothing to do with executing him by hanging. It is an allusion to the albatross in The Rime of the Ancient Mariner. This is a once-common English metaphor and thirty years ago most Americans and Brits would have instantly recognized its origin (as I did).
Here, however, the sailors change their minds again and blame the Mariner for the torment of their thirst. In anger, the crew forces the Mariner to wear the dead albatross about his neck, perhaps to illustrate the burden he must suffer from killing it, or perhaps as a sign of regret ("Ah! Well a-day! What evil looks / Had I from old and young! / Instead of the cross, the albatross / About my neck was hung").

It is not what Romney actually said nor it’s intended context that worries me. It is the deafening silence. I recall days of front pages misinterpreting the proper use of the word niggardly. We have seen Macacca turn George Allen, front runner, into a who said that. We have seen both Biden and Clinton make severe racial slurs against the BHO then be gently chastised and forgiven. I note that Romney seems to fall into the same camp with Biden and Clinton.
