DISSATISFACTION WITH the economy, expressed in spasms of anger toward Wall Street and Washington; the dashed hopes of many who believed that Barack Obama’s election would create a new spirit of unity; and genuine uncertainty about Democratic health care reform — all of these have created an historic opportunity for the Republican Party.

◼ Boston Globe endorses Huntsman: For vision and national unity

Among the candidates, only two stand out as truly presidential, Mitt Romney and Jon Huntsman. Both have track records of success, and both, through their policies and demeanors, have shown the breadth of spirit to lead the nation. But while Romney proceeds cautiously, strategically, trying to appease enough constituencies to get himself the nomination, Huntsman has been bold. Rather than merely sketch out policies, he articulates goals and ideals. The priorities he would set for the country, from leading the world in renewable energy to retooling education and immigration policies to help American high-tech industries, are far-sighted. He has stood up far more forcefully than Romney against those in his party who reject evolution and the science behind global warming.

With a strong record as governor of Utah and US ambassador to China, arguably the most important overseas diplomatic post, Huntsman’s credentials match those of anyone in the field. He would be the best candidate to seize this moment in GOP history, and the best-prepared to be president.
