From
Mark Halperin and John Heilemann’s Double
Down – Game Change 2012 (New York: Penguin Press, 2013), p. 243:
“The
choice in the Republican Party has come down to the dog-on-roof guy or the
man-on-dog guy? [McCain] said. “I’m with
the dog-on-roof guy.”
. . .
(McCain
was referring to how Romney once strapped his dog to the top of the car for a
long drive during a family vacation, and how Santorum compared gay sex to men
having sex with dogs.)
