In his tearful admission this morning, South Carolina Governor Mark Sanford said he had been unfaithful to his wife with a "dear friend" from Argentina, with whom he had "developed a relationship." "It began very innocently...," said the one-time would-be GOP hopeful, "in just a casual e-mail back and forth..."

No pronouns. No hints at a gender. Just a dear friend he met over the internet. Fine. If he wants us to fill in the blanks with our imaginations, so be it.

What do you imagine this "dear friend" to be?

UPDATE!: She's a she.
