Barney Frank casts GOP candidates for 'The Wizard of Oz'

Retiring Congressman Barney Frank (D-MA) joked Sunday that he was casting a remake of "The Wizard of Oz" starring Republican presidential candidates.

"I look at the Republican debate -- I've been casting 'The Wizard of Oz,'" Frank told ABC's Christiane Amanpour. "Obviously, Mitt Romney is the tin woodman without a heart, and Rick Perry is clearly the scarecrow."

"Let me just say about Rick Perry: He illustrates the point that what's scary about some people is not what they don't know, but what they know that isn't true. I just heard this ad which he said, some liberals say faith is a sign of weakness. That is just bizarrely delusional."

He continued: "Newt [Gingrich] is the Wizard of Oz. I just think Newt, there's nothing there."

"I think he's ginned up this whole big thing, but when people focus on him, as opposed to him being the not-Romney, this is a man who served as speaker, was a relative insider, he was twice reprimanded by House -- by the way, I was reprimanded by the House, one of the reasons I wouldn't run for president. There was a problem with the marriages. There is this incredible hypocrisy of criticizing Chris Dodd and me because we weren't doing anything about Freddie Mac when we were in the minority. We did when we were in the majority. And he was taking money from them when the Republicans were in the majority to make sure that nothing happened. I just think that he is an obvious weak candidate."

At a press conference announcing his retirement last week, Frank said he welcomed Gingrich's rise to Republican frontrunner.

"I did not think I had lived a good enough life to be rewarded by Newt Gingrich being the Republican nominee," Frank told reporters. "I look forward to debating — to take one important example — the Defense of Marriage Act with Mr. Gingrich. I think he is an ideal opponent for us when we talk about just who it is that is threatening the sanctity of marriage."

Gingrich, who supports the Defense of Marriage Act and opposes same sex marriage, has been married three times himself.

"He would be the best thing to happen to the Democratic Party since Barry Goldwater," Frank concluded.
