Don Lemon Racist?

CNN's Don Lemon engaged in some pretty racist "code words" Sunday night when he used the term "monkey-wrench" to describe the "problems" the GOP is supposedly having (oh boy).  Of course not being a typical reactionary, knee-jerk liberal who absolutely love to keep racism alive by accusing everyone but themselves of it, I know exactly what Lemon meant.  But had this been Rush Limbaugh, Sean Hannity or Bill O'Reilly, is there any doubt how fast Al Sharpton, Chris Matthews or Toure Neblitt would be jumping on this and calling for the dismissal of said conservative?
