Tuesday night’s Republican presidential debate wasn’t the most entertaining, but it was by far the most educational. The two-hour session gave the candidates a chance to critique the Obama record, as well as tease out some policy differences in illuminating ways.
Start with trade, which showcased Donald Trump. “I love trade. I’m a free trader, 100%,” said the businessman, after declaring that he opposed the only free-trade deal currently on offer, the U.S. agreement with 11 other Pacific nations.
Mr. Trump called it a “terrible deal,” though it wasn’t obvious that he has any idea what’s in it. His one specific criticism was its failure to deal with Chinese currency manipulation. But it took Rand Paul to point out that China isn’t part of the deal and would be happy if the agreement collapsed so the U.S. would have less economic influence in Asia.
Mr. Trump said on these pages Tuesday that he would label China a currency manipulator on his first day as President, triggering tariffs on thousands of Chinese goods. The businessman thinks economic mercantilism is a political winner, but we doubt that starting a trade war that raises prices for Americans would turn out to be popular. Many of Mr. Trump’s supporters care more about his take-charge attitude than his policies, but GOP voters are going to have to decide if they want to nominate their most protectionist nominee since Hoover.
