The Atlantic: “Newt Gingrich, Cheerful Zombie”
Molly Ball writes in The Atlantic, March 27, 2012: “Newt Gingrich, Cheerful Zombie”
“Gingrich these days is the walking dead, politically speaking, but he is a cheerful zombie, seemingly at peace with the way things have played out and satisfied to amble through the rest of the primaries and see how he does. “
The article also refers to Gingrich as “stranded on earth” and I would note the connection of zombie metaphors to alien metaphors.
