Elizabeth Warren built her brand for the 2020 presidential primary on wonkery. From childcare to housing to higher ed, Warren has leveraged decades of economic policy expertise and a network of liberal intellectuals many of them former students in Warrens law school classes to propose ambitious, meticulously detailed reforms.

The trade platform Warren unveiled Tuesday in Detroit is a little different. It retains Warrens wonk-flair with a proposal to reorganize the disparate trade regulators currently scattered throughout the Washington bureaucracy inside a single, consolidated agency. But the heart of her proposal is ideological rather than technical. Warren is making a crystal-clear statement of principles, and an equally plain break with the past 30 years of American trade policy up to and including the presidency of Donald Trump .

America chose to pursue a trade policy that prioritized the interests of capital over the interests of American workers, Warren told a crowd in Detroit Tuesday. We have encouraged companies to invest abroad, ship jobs overseas, and keep wages low. All in the interest of serving multinational companies and international capital with no particular loyalty to the United States.
