“…Large literatures show that voters have strong opinions about trade and immigration that reflect a mixture of their interests (Ardanaz, Murillo, & Pinto, 2013; Baker, 2005; Scheve & Slaughter, 2001) and values (Hainmueller & Hiscox, 2007; Hainmueller & Hopkins, 2015; Mansfield & Mutz, 2009). Voters’ exposure to international trade and immigration flows has also been found to have important electoral impacts (Baerg, Hotchkiss, & Quispe-Agnoli, 2018; Colantone & Stanig, 2018; Jensen, Quinn, & Weymouth, 2017; Margalit, 2011; Mayda, Peri, & Steingress, 2018). In short, trade and immigration are mass political issues.…”
