Running on Their Own

Abstract

Senators who first reach office by gubernatorial appointment are successful at the polls at half the rate of incumbents in general. Outcomes of elections featuring appointed senators are affected by the incumbent's voting record in the Senate, the divisiveness of the primary, state partisanship, the size of the state, national political conditions, and the quality of the challenger. This last factor is the key to understanding the anomaly, as appointed senators face higher quality challengers than do senators who first gain office through the electoral process.
