Did Haley Barbour make an assassination joke about Obama?

The other day we reported that former repugican cabal chairman Haley Barbour, of Mississippi, made a sick racist comment about phsyically abusing President Obama:

Barbour offered a brief assessment of the repugican national cabal. “While I would love for [Chris] Christie to put a hot poker to Obama’s butt,” said Barbour of the rnc keynote speaker, “I thought he did what he was supposed to do.”

A reader pointed out something far worse than the already-incredible racism that underlies a southerner with a history of racist problems suggesting that a black man be branded. A reader writes:

Politico has completely missed the disgustingly homophobic angle on Haley Barbour's comment to donors that Chris Christie should have "put a hot poker to Obama’s butt."
How obsessively bigoted is this man? A hot poker shoved into the anus and bowels is the reputed method used to assassinate King Edward II of England because he had a male lover.
How does an infamous method of murdering a gay man centuries ago make it's way into that man's working vocabulary?

Not just a notorious method of murdering a gay man, but the method of murdering a head of state, otherwise know as assassination.

Did former repugican cabal chair Haley Barbour intend to joke about assassinating the President of the United States or was he simply being viciously racist, and following in the footsteps of Mitt Romney's recent birther joke and the current rnc chair Reince Priebus trying to paint the President as "foreign"?

These are the people who want the keys to the national car. Apparently they haven't matured any since the last time they wrecked it.

UPDATE: Barbour apologized for the comment. Too late - Damage done.
