Chelsea Clinton just bagged a superdelegate for her mother. The youngest Clinton is campaigning today in San Juan, Puerto Rico. A few moments ago, at the Universidad del Sagrado Corazon, Luisette Cabanas, an unpledged superdelegate, announced her support for Clinton, giving the campaign the majority of automatic** delegates on the island.

Chelsea and her entourage are being hosted by superdelegates Fransisco Domenech and Senate President Kenneth Mclintock.)

** Obama supporters don't use the word "automatic" anymore, not even, I'd suspect, in normal conversation. So here's what I'll do: when Clinton picks up a superdelegate, I'll use the A-word. When Obama picks up a superdelegate, I'll use the S word. The semiotic complexities of the Democratic primary race are confusing.
