We keep getting mixed signals about how seriously to take the Democrats’ protectionist rhetoric. The most optimistic spin is that the corporate-tax plan, whether or not it’s a good idea, is a fairly modest way to pander to protectionist sentiment. I doubt Kerry is really going to do much with that promised review of existing trade agreements. On the pessimistic side: Even Bill Clinton plumped for more trade “enforcement actions” on Monday night (as Kerry also has); the Democrats want no new trade agreements without conditions that make it very hard to envision the agreements being reached; and Kerry’s objection to Bush’s steel tariffs is not that he imposed them but that he later rescinded them. Free traders can reasonably vote for Kerry on the theory that he’s better on other issues that they care about. But free traders who say that he will be better on trade than Bush are just deluding themselves.
