The push for the Trans-Pacific Partnership (TPP) is reaching its final stages, with the House of Representatives soon voting on granting the president fast-track trade authority, which will almost certainly determine the pact’s outcome. The proponents of the TPP are clearly feeling the pressure as they make every conceivable argument for the deal, no matter how specious.

In the last few weeks, TPP advocates have repeatedly tripped up, getting their facts wrong and their logic twisted. This hit parade of failed arguments should be sufficient to convince any fence sitters that this deal is not worth doing. After all, if you have a good product, you don’t have to make up nonsense to sell it.

Leading the list of failed arguments was a condescending editorial from USA Today directed at unions that oppose the TPP because they worry it would cost manufacturing jobs. The editorial summarily dismissed this idea. It cited Commerce Department data showing that manufacturing output has nearly doubled since 1997 and argued that the job loss was due to productivity growth, not imports.

It turned out that the table used in the editorial did not actually measure manufacturing output. The correct table showed a gain of only 40 percent over 17 years. By comparison, in the prior 10 years, when our trade deficit was not expanding, manufacturing output increased by roughly 50 percent.

USA Today eventually acknowledged the error but left the text and the criticisms in the editorial unchanged. Remarkably, the headline of the editorial referred to the opposition to the TPP as a “fact-free uproar.”

Another big swing and miss came from Bill Daley, a former commerce secretary under President Bill Clinton and a former executive at JPMorgan Chase who briefly served as chief of staff in Barack Obama’s administration. Daley published a New York Times column pushing the TPP by arguing for the virtues of trade. The piece was chock-full of errors and misleading comments, with the best line being the claim that the United States ranks near the bottom in the ratio of exports to GDP because of the barriers put up to our exports.

As fans of trade economics everywhere know, the main reason the United States has a low ratio of exports to GDP is that the United States is a big country. This means that Illinois and Ohio provide a large market for items produced in Indiana. On the other hand, if the Netherlands or Luxembourg wants to have a large market for its products, it must export. (Paul Krugman added a chart to illustrate this point.)

Then there was the issue over whether the TPP is secret. Obama and other TPP supporters ridiculed this notion, pointing out that members of Congress can see the draft text anytime they like. But the critics’ point is that it is impossible to have a public debate on the TPP because the members are not allowed to take staffers with them or discuss the text with others.
