Shortly after Bill Clinton took office, Limbaugh had a short-lived syndicated TV show. In a widely reported incident that I viewed personally, he talked about Socks the cat and then asked his audience, "did you know there's a White House dog?" For his punchline, Limbaugh showed a photo of a 12-year-old Chelsea Clinton.
It takes a special breed of jerk to go after the under-age child of a politician who was new to the national spotlight and not participating publicly in any political events. To expose her to ridicule for her looks, at what is easily the most awkward stage of adolescence, is completely indefensible.
