MOUNT DORA, Fla. -- Newt Gingrich on Thursday dramatically ramped up his attacks on Mitt Romney, saying the former Massachusetts governor is guilty of lies, desperation and hypocrisy that should make "every American angry."
Gingrich, the former House speaker, said he was infuriated by a barrage of attack ads that are blistering him on Florida TV stations ahead of Tuesday's GOP presidential primary. Most are funded by an outside organization backing Romney, but some are from Romney's own campaign. Unable to match Romney's money machine, Gingrich implored Florida Republicans to punish his chief rival for what Gingrich called callously dishonest ads.
"This is the desperate last stand of the old order," Gingrich told an outdoor crowd of more than 1,000 northwest of Orlando. "This is the kind of gall they have to think we're so stupid and we're so timid."
The nature and volume of the attack ads are similar to those that badly damaged Gingrich in Iowa a month ago.
"I think all the weight of his negative advertising and all the weight of his dishonesty has hurt us some," Gingrich said. But "I am not going to allow the moneyed interests that are buying those ads to come in here and to come into other states to misinform people and then to think we are too dumb to fight back."
Romney steered clear of his rival during a subsequent campaign appearance.
Gingrich later told reporters he decided to sharpen his criticisms after Romney's tax returns showed investments held in Cayman Island accounts, the government-backed mortgage company Freddie Mac and other entities.
"Here's a guy who owns Freddie Mac and Fannie Mae stock," Gingrich said. "He owns a Goldman Sachs subsidiary, which is foreclosing on Floridians. And on that front he decides to lie about my career? There's something about the hypocrisy that should make every American angry."
Romney has been hammering Gingrich for consulting work he performed for Freddie Mac and telling Florida voters that Gingrich was paid by a company that contributed to the state's poor housing market.
The acerbic remarks came three days after Gingrich took a much more moderate tone in a televised debate in Tampa, when Romney sharpened his own attacks. Gingrich strongly hinted he will be more aggressive in a CNN debate scheduled for Thursday night in Jacksonville.
Romney, meanwhile, toured a Jacksonville factory that is closing because of the economy before he addressed several hundred people gathered outside. He acknowledged that the live audience at Thursday's debate may be fairly raucous, a dynamic that seems to favor Gingrich and his populist, us-against-the-media and us-against-the-establishment style.
