 Julian Castro. Adam Frisch, a Democrat running for Colorado's third congressional district. He's not even in office and he's trashing Biden. Michael B. Moore, the Democrat nominee running against Nancy Mace in South Carolina. James Carville, longtime Democrat strategist, advisor to President Clinton. He's the one, the Ragin' Cajun, as they called him. He's the one that coined the term, it's the economy, stupid.
