“I think the people of Florida will prefer big solutions to small negative attacks,” Gingrich said in an interview on ABC’s “Good Morning America.” “And I think in the end, just as happened in South Carolina, Governor Romney’s liberal record in Massachusetts, plus the style of his campaign, will end up, I think, having him lose.”

Gingrich, who is riding high after his 12-point win over Romney in Saturday’s South Carolina primary, told ABC’s George Stephanopolous that heading into the Sunshine State’s primary, he plans to focus his criticism on Romney’s implementation of the 2006 Massachusetts health care law.

”I’m going to talk about Romneycare,” he said. “I’m going to draw a contrast between Romneycare and Obamacare, which are virtually identical, and what I would do in developing patient power and allowing people and their doctors to be in charge.”

The former House speaker also renewed his effort to define himself as a political outsider, arguing that “you’re going to see the establishment go wild the next week or two” in response to his surging bid.

“The idea of a Gingrich presidency actually changing Washington, of my ignoring all the powers that be — I have no ties to Goldman Sachs, for example, the biggest single backer of Romney; I have no ties to the power structure,” he said. “I think that they are very frightened at the idea of a genuine outsider. And I’ve managed to remain a genuine outsider because I’m a Reagan populist conservative and have been for my whole career.”
