In election years, ballot box success for governors also helps presidential candidates, but not the other way around

The US is not just electing a new president in 2016 – in 12 states voters will also be able to choose their next governor. In new research, Amuitz Garmendia Madariaga and H. Ege Ozen examine how presidential and gubernatorial candidates’ electoral fortunes are intertwined. They find that voters are more likely to cast a straight ticket ballots in presidential election years, and that successful gubernatorial candidates actually provide a vote boost for presidential candidates at the state level, not the other way around.
