Republican presidential candidate Herman Cain might be in the midst of his campaign’s first crisis, all thanks to ice cream.

Now leading in at least one national poll, Cain is frequently asked if he is the new political flavor of the month. Cain’s canned response is: “Haagen-Dazs black walnut tastes good all the time.”

Here’s the problem: Haagen Dazs no longer makes black walnut ice cream. It was a limited edition, and is no longer available. So, in a manner of speaking, you might say that Haagen Dazs black walnut was – by definition – a flavor of the month.

When contacted by ABC News, Hazel, at the Haagen-Daz customer service line, said, “We don’t sell black walnut. The sales nationally did not meet our expectations, unfortunately. It did not behoove us to continue with the product.”

The ice cream did not meet expectations. Cain better hope that is not a metaphor for his candidacy.
