In an interview after the event, Mr. Rolph said he was impressed by Mr. Obama, but he had yet to decide who he would support. When would he make up his mind? “Probably the moment I walk into the caucuses,” he said with a smile.

Is the "who" instead of "whom" an error or a policy? I see this case error so often that I begin to believe it's one of those gauche-grammar choices newspapers make such as omitting a comma from the last item in a series or the possessive before the gerund even though the NYT Style Book warns to use it.
