She appears to have Kristof dead to rights here.
Allahpundit lays out the amazing timeline. First Huckabee releases a rapist who rapes again and is convicted and then we get this:
Which leads us to the punchline:
Mr. Huckabee, I have read “you” Chief of Staff’s letter. While I wish I could say that I am LOL — ROTFLMFAO, in fact — I’m not. We have four dead police officers here. And the stunning evidence of the cavalier manner in which your Chief of Staff blew off the polite and valid concerns of a prosecutor will, I hope, convince voters that you are not someone who can be trusted with another executive position. Surely not the top one in the land.
UPDATE: These guys really didn’t get along, as this article from a few years later makes clear:
Now, Governor Huckabee is involved and issued this statement: “I know Phil Mask to be an effective sheriff who isn’t part of the good ol’boy political machine. It is obvious to me that ‘Headline Herzfeld’ couldn’t resist an opportunity to get back up on the stage even though the voters of Arkansas rejected his kind of stunts when they voted him off the island in the primary for Attorney General. Perhaps Sheriff Mask will investigate Herzfeld’s use of drug task force money he used to do public relations work outside his district.”
This makes the contempt in the letter believable.
UPDATE x2: Further confirmation in the form of a contemporaneous account.
