I'll see your ad and raise you an endorsement

A big endorsement for Obama from someone who has the inside scoop on international threats to the U.S., Senator Jay Rockefeller:

As Chairman of the Senate Intelligence Committee, I am all too aware that the threats we face are unconventional. They are sophisticated. They are constantly changing and adapting. And they are very serious. What matters most in the Oval Office is sound judgment and decisive action. It’s about getting it right on crucial national security questions the first time – and every time.

Four other superdelegates endorsed Obama earlier today.
