Reason's blog Hit & Run has cracked the mystery of what Jim Cavezial is mumbling in Aramaic at the beginning of the Michael J. Fox response ad:
"You betray me with a kiss." So now we have actors responding to actors with biblical references that are both vaguely threatening and completely irrelevant, spoken in an obsure Middle Eastern language that a maximum of three people in all of Missouri understand. This is an election cycle like no other.
More seriously though, what the heck were they thinking? I'm guessing that we're dealing with some sort of code-talking here, but directed to whom? Unsettling.
