The rumored superdelegate support looks to be true:

Clay Confirms Obama Has 50 New Superdelegates -- Political Wire

Rep. Lacy Clay (D-MO), Sen. Barack Obama's Missouri co-chairman and pledged Obama superdelegate, said Obama will gain the support of 50 undecided Democratic superdelegates later this week, according to the Columbia Missourian.

Said Clay: "She (Sen. Clinton) will not make up those numbers. This race is over."

Former NBC News anchor Tom Brokaw first reported yesterday that Obama had about 50 secretly committed superdelegates.
