AS IT TOOK THE UR TO PASS W'S DEAL, SO MAY IT REQUIRE JEB TO PASS THE UR'S:

What appear to be the main remaining bones of contention are varied and tricky. Canada, where an election has just been called for October, does not want to open up its market for dairy products--a priority for New Zealand, one of TPP's originators a decade ago. Liberalising Japan's agricultural market, notably for rice, remains acutely sensitive politically. Mexico objects to the amount of content from countries not in the TPP that Japan wants allowed into its exports of lorries. America protects its sugar producers. And it wants its pharmaceutical firms to enjoy 12 years of patent protection on new biologic drugs, which most of the other 11 countries find several years too long.

Yet hopes had been high that the Hawaii talks might bring this marathon negotiation to the finishing line. They were the first between ministers since the American Congress narrowly voted to give the president "fast-track" Trade Promotion Authority (TPA), meaning that Congress could no longer unpick a trade agreement clause by clause, having to approve or reject it as a whole. Without TPA, other countries had been unwilling to make their best offers. Now, however, some speculate that, in the intense haggling to secure passage of TPA through Congress, the administration made promises that have hamstrung its negotiators. Another reason for believing the Hawaii round might be crucial was the pressure of the American political calendar. The administration has to give Congress at least 90 days' notice before signing a trade agreement. So time is already running out if TPP is to be sealed before becoming embroiled in next year's presidential election campaign. Even some of the most optimistic TPP supporters think a deal may now not happen until 2017 at the earliest.
