This paper exploits the 1968 U.S. Supreme Court decision to strike down Ohio's ballot access laws as a natural experiment to overcome the endogeneity problem. The evidence from difference-in-difference esti- mations suggests that the court decision and the accompanying sharp decrease in Ohio's petition requirements resulted in major parties facing a signifficant increase in competition from third party and independent candidates.
