Despite Big Victory, Romney Won't Let Up on Gingrich MINNEAPOLIS - On a three-hour flight from Minneapolis to Florida, where he picked up the state's 50 delegates Tuesday night in a big primary victory, an ebullient Mitt Romney came to the back of his private plane to chat with his traveling press corps. "Wow, what a night, huh?" said Mr. Romney, clad in jeans and white dress shirt. If they all go like that I'll feel pretty good. I obviously feel terrific. Mr. Romney, who waged a particularly negative and aggressive campaign against Newt Gingrich in Florida, showed no signs of easing up on him, at least in the short term. When asked if a line from his victory speech Tuesday night - about how a heated primary won't divide the Republicans but would simply make each candidate stronger - still held true if the fight continued all the way to the convention, Mr. Romney willingly brought up Mr. Gingrich, the former speaker of the House, attacking his conservative credentials while promoting his own. "I really think that the fact that conservatives in Florida said they supported me makes sense," Mr. Romney said, before laying into Mr. Gingrich's record on things like climate change and Medicare reform: "I'm the guy that refused to sign a cap and trade bill in New England. The speaker sat down with Nancy Pelosi on cap and trade. So who's the conservative in that one? How about making sure that Medicare is fiscally solvent? I put a proposal out, which now Wyden and Ryan have taken on legislatively. When Paul Ryan put his plan out in the first place, I said it was a major advance, a big step forward, we were on the same page. Speaker Gingrich called that right-wing social engineering. Who's the conservative on that one? I mean his big idea in the last campaign was building a colony on the moon. Spending that kind of money I don't consider conservatism. And by the way, there's only one person on the stage that's argued for a national health care mandate as late as 2009. That was Speaker Gingrich. He concluded, somewhat incongruously: "So I'm not saying he's not conservative. I'm just saying he's not the pure conservative he would have people believe, and I think the folks in Florida saw through that. Mr. Romney, who did not get a congratulatory call from Mr. Gingrich after his Florida victory - "You know, it doesn't bother me in the slightest," he said - said he expected Mr. Gingrich to command some of the spotlight in the next round of contests, whether or not Mr. Romney keeps the pressure on him. "I think the speaker will get ample airtime whether I'm talking about him or talking about other issues," Mr. Romney said. You know, I don't know what he'll be saying in Minnesota, or what he'll be saying in Nevada, but we've seen a pattern of him going to each state and making promises of the things he'll do for that state. Mr. Romney also accused Mr. Gingrich of pandering to the various early nominating states. "He's just gone from state to state to state, he's taken an issue that is a local issue and said he's all in favor of it," Mr. Romney said. We have not heard from him how he's going to balance the budget. It's instead been a campaign of promises, and what he calls bold ideas, but which are primarily satisfying the interests of the local population. "There's nothing wrong with helping people that have concerns and challenges in the state, but it begins to be a pattern when you see it state after state after state, and you recognize the reason we're in the trouble we're in is because of politicians who promise stuff to everybody they see," Mr. Romney added. When asked about a comment made earlier Wednesday morning to CNN, in which he said, "I'm not concerned about the very poor - we have a safety net there," Mr. Romney said his remark needed to be viewed in its full context. "I've said throughout the campaign, my focus, my concern, my energy is going to be devoted to helping middle-income people, all right?" he said. We have a safety net for the poor in the country, and if there are holes in it, I will work to repair that. And if there are people that are falling through the cracks, I want to fix that. He added: "But my focus in the campaign is on middle-income people. Of course I'm concerned about all Americans - poor, wealthy, middle class, but the focus of my effort will be on middle-income families who I think have been most hurt by the Obama economy.
