Sarah Palin: Rick Perry Flat Tax Will 'Gain Momentum'

Sarah Palin praised Texas Gov. Rick Perry's flat tax plan Thursday evening in an interview on "The Sean Hannity Show" on Fox News.

"Rick Perry -- now coming out with, really embracing Steve Forbes' flat tax idea -- that's going to gain momentum. I look forward to hearing more of the details," she said. "In fact, when I heard that Rick Perry was embracing of Steve Forbes' idea, I went into my garage and dug out an old book from 1999 that Steve Forbes had written," she said. "Many aspects of it make so much sense," added the former Alaska governor and 2008 vice-presidential nominee, who declined to run for president in 2012.

Perry said Wednesday that he would be unveiling a flat tax. "I want to make the tax code so simple that even Timothy Geithner can file his taxes on time," he quipped, referring to the Treasury secretary's failure to pay over $34,000 in taxes while working for the IMF, which was revealed during his Senate confirmation hearings. Perry will unveil specifics of his plan next week.

Palin also commented on another GOP candidate with a simple tax plan: Herman Cain. "Again whether you believe or can really embrace all of that 999 plan, at least he has got the ball rolling, saying we must reform our tax code today because it is a monstrosity," she said, referring to the former Godfather's Pizza CEO's plan to have a nine percent corporate income tax, nine percent personal income tax and a nine percent national sales tax. "Well, definitely I would tweak it -- because I believe that in order to get rid of crony capitalism and corporate welfare and the corruption and waste in the federal government, we need to get rid of the corporate income tax which chases jobs overseas," she said.

Palin again praised former House Speaker Newt Gingrich for his debate performance. "Well you know, Newt has been in the trenches; he seems to have seen it all, and his calm, cool, collected demeanor I think bodes well for these debates."
