Local political institutions and electoral context influence levels of campaign spending in mayoral elections

Campaign spending is a perennial concern in both national and local elections, especially since the 2010 Citizens United Supreme Court ruling. Proponents argue that more spending increases interest in elections, while detractors claim that it creates biases in representation and public policy. Using an original dataset, Aaron C. Weinschenk examines campaign spending levels in mayoral elections, finding that the electoral context and local political institutions play the most important role in shaping levels of campaign spending across city elections. From these results, he identifies several ways to reduce campaign spending in mayoral elections, but notes that these changes may have unintended consequences. If levels of campaign spending decline due to institutional changes, cities elections, which often suffer from low voter turnout rates, might experience even lower levels of turnout.
