Gov. Jerry Brown, D-Calif., said Sunday that Democrats haven't been "clever enough" to deal with the effects of a changing global economy.

"Leadership has not been clever enough, or strong enough, or perhaps visionary enough," Brown told "Meet the Press" host Chuck Todd on NBC.

Democrats "have been the champion of working people," but "haven't been able to deliver in [the] face of these global trends," the outspoken governor of the Golden State said.

"It takes a certain vision, how the hell do we get out of this? And it takes some political skill at the same time," he said.

Brown also said the Democratic base is shifting and is in some ways unrecognizable. "I don't know who this Democratic base is. It's shifting. The segments of our party are highly differentiated," he said.
