General Findings
Competition Varies Among Levels of OfficeTailor reforms to the office
Reforms Can Have Seemingly Perverse Effects on Competition
Example: Clean Elections encourage candidates to run where they have little chance of winning, which increases levels of constestation, but lowers overall levels of competition
Reforms Can Create Perverse IncentivesExample: Term Limits encourage candidates to wait for open seats
Reform Recommendations
There is no magic bullet, the electoral process is complicatedYou may only get one chance to get it right, choose wiselyConsider combining state constitutional amendments with statutes to fill in details and to provide flexibility if something doesn’t work as planned
