In his 2010 book “No Apology: The case for American Greatness,” Romney argued against protectionism, an ideology that favors tariffs, quotas and other restrictions placed on international trade.

“Personally, I don’t like to see America lose any good jobs,” Romney wrote. “But when I see an American company challenged by a foreign competitor, I don’t look for protectionist policies as an answer to the company’s problems. Instead, I look to see how that company can become competitive once more, drive off its foreign foe, and propel its own products into foreign markets.”

But during the 2012 presidential campaign, Romney has taken the opposite position.

During an Oct. 24 radio interview with the Fox News Channel’s Sean Hannity, for instance, Romney promised that on “day one” of his presidency he would impose new tariffs on trade with China, and classify the nation as a “currency manipulator.”
