The Economist | Cites research by Alex Hertel Fernandez (PhD '16), Assistant Professor of International and Public Affairs at Columbia University:
Forthcoming research by Alexander Hertel-Fernandez of Columbia University suggests that limits on collective bargaining, which are mainly aimed at public-sector unions, made government workers in Indiana and Wisconsin less likely to take part in political campaigns, or to vote. In a study of 111 border counties in Indiana, Michigan and Wisconsin, he also calculates that the right-to-work laws they introduced between 2012 and 2016 could account for two percentage points of Mrs Clinton’s underperformance in those states compared with Barack Obama in 2012. Given that Mr Trump’s victory in the electoral college was based on a combined total of 70,000 votes across Michigan, Pennsylvania and Wisconsin, that could have cost her the presidency.
