From a Gail Collins op-ed piece in the NYT (2/24/11, p. A27), “Revenge of the Pomeranians”:
Also, why is the federal government in danger of shutting down? Whom can I blame for this? Does it have anything to do with what’s going on in Wisconsin? Did Congress pass a budget last year at all? Why not?
The whom caught my eye. It’s prescriptively “correct”, since the lexeme WHO is serving here in an object function (in this case, it’s the direct object of blame), but still it was jarring to me, especially in the context of Collins’s breezy and informal style. (Not that Collins was necessarily responsible for the whom in this column; it might have been introduced by an editor.)
