Abstract
Left-wing opposition to globalization lives, among voters and interest groups, both labor and progressive. But have left-wing opponents of trade successfully cultivated representation? Using the US Congress as a case, I show that two distinct groups of Democrats vote in characteristically progressive and protectionist ways on trade bills. These groups, especially progressives, are rewarded with excess campaign contributions from publicly anti-trade groups. A dyadic research design shows that interest group/representative relationships degrade noticeably when members of Congress vote for trade bills that interest groups have opposed. While recent events have highlighted business interests and right-wing economic populism, left-wing opposition to globalization remains a vibrant third face of contemporary domestic contestation over trade that will be especially important where populists fade.

Notes
1 On opposition to trade from labor unions, see Jansa and Hoyman (Citation2018), Saltzman (Citation1987), Engel and Jackson (Citation1998), Jackson and Engel (Citation2003). On opposition to trade from the progressive left, see Ehrlich (Citation2010, Ehrlich, Citation2018), Postnikov and Bastiaens (Citation2020), Bastiaens and Postnikov (Citation2020).
2 The complex effects of trade can complicate simple mappings from labor to the left and business to the right (McKibben & Taylor, Citation2020). Labor and capital stuck in uncompetitive industries might target one party jointly, for example. Right-wing politicians use opportunistic appeals on trade to attract workers, too. The highly articulated preference heterogeneities within factors and industries that characterize 21st century trade politics make exceptions to the labor-left and capital-right tendencies especially common. Still, these tendencies are observed frequently across countries and over time, and provide a useful structure for understanding the partisan politics of materially driven trade opposition.
3 Note that the claim here is not that labor is uniformly protectionist; workers in some occupations, industries, or firms may be quite pro-trade. The only claim is that workers or unions that are opposed to trade will generally use left-wing parties as a vehicle for their concerns because of left-labor links.
