Mitt Romney’s convincing victory erased his earlier defeats and perhaps any serious obstacle to his nomination. The question that still troubles party leaders, however, is the damage he will sustain before returning to Tampa in September for their convention.
Triumph could cost Romney much more than the million dollars or so that bought each point of his 46-32 margin over Newt Gingrich. Already the former speaker has shaped the plutocratic image of Romney now visible in national polls. Now a furious, wounded Gingrich could go still further — demanding, for instance, that Romney release many more years of tax returns.
