Carville leveled the bizarre charge after claiming that Republicans had written Miller's speech, even though it contained lines Miller had used before and echoed much of the criticism of Democrats outlined in Miller's recent book, "A National Party No More."

But Carville insisted the renegade Democrat's speech was strictly a put-up job.

"They got that poor man in the twilight of his career and just used him," the former Clinton adviser insisted. "They said, 'Look, go up there and say this,' and they handed him a bunch of documents."

Carville claimed Miller didn't know "what he was talking about" in post-speech interviews, saying that's why he grew angry when challenged by MSNBC host Chris Matthews.

When Imus noted that the Georgia Democrat sounded "fine" when he interviewed him the next morning," Carville shot back: "They probably shot him up with something, you know. He just likes screaming at people."
