Former White House Chief of Staff John Sununu Monday ridiculed filmmaker Michael Moore's claims that freshman Rep. Alexandria Ocasio-Cortez, D-NY, is her party's new leader, commenting she is "quantitatively ignorant" on the issues.

"One can only pray for the first time in his life Michael Moore is right," Sununu told Fox News' "America's Newsroom." "That would be good for the Republican party. It would be good for the country, and frankly, it finally would allow people to start looking at the reality of the difference between sound policies and insane policies that will lead this country to socialism."

Moore Sunday lamented the constitutional requirement that presidential candidates must be at least 35, commented that "everybody knows" Ocasio-Cortez is the new party leader.

"The minute she has to support what she is talking about with significant numbers she falls apart," Sununu said. "She doesn't know the difference between a million, billion, and a trillion. The more public this is seen as being the kind of Democratic Party there is, the quicker the country will come back in the relatively short run to the middle and then we can have a debate between rational Democrats and Republicans."

Sununu said the Democrats' move to the left, as shown by the rise of Ocasio-Cortez, is overshadowing more "reasonably rational" party members like Howard Schultz and Michael Bloomberg.

"It is a battle between ideology but it is also a generational battle," said Sununu, and he thinks it's being egged on by the liberal press.
