Someone should tell CNN that superdelegates don't count until they actually vote:

Sen. Barack Obama inched closer to the Democratic nomination Tuesday as endorsements from superdelegates trickled in.

Sen. Barack Obama is closing in on the 2,118 delegates needed to clinch the nomination. Obama is now four delegates short of the 2,118 needed to clinch the Democratic presidential nomination, according to CNN's count.

I wonder if they are counting Teddy Kennedy and Robert 'KKK' Byrd, both of whom have declared for Obama (and may not be well enough for the convention).

UPDATE: CNN just declared Obama the winner, even though no superdelegate votes have been cast.
