NOW that John McCain is, formally, the presumptive presidential nominee of the Republican Party, he can stop worrying about winning primaries and caucuses and start worrying about winning over conservatives. Mr. McCain still faces a large challenge from his right in the fall, as many conservatives suspect he isn’t really one of them.
To prove his bona fides as a conservative, Mr. McCain and his defenders often cite his support for free trade. A writer in National Review, for example, suggested last year that conservatives should support Senator McCain because he is, in Mr. McCain’s own estimation, the strongest free trader in the Senate since Phil Gramm (an adviser to Mr. McCain) left that body.
Mr. McCain may be a conservative. But his unbridled free-trade policies don’t help make that case.
Free trade has long been popular with liberals, and it remains so with liberal elites today. The editorial pages of major newspapers consistently support free trade. Ted Kennedy supported the advance of free trade. President Bill Clinton fought hard to win approval of the North American Free Trade Agreement. Despite some of his campaign rhetoric, Barack Obama is careful to express qualified support for free trade, even when stumping in the industrial Midwest.
