Do incumbents have an electoral advantage and if so, do these advantages differ across gender? In this study, I estimate the electoral advantages enjoyed by incumbents in 10 Canadian federal elections, across 3059 ridings, from 1990 to 2021. Using a regression discontinuity design, I compare men and women who have very narrowly won or lost elections on three different indicators: propensity to run again, probability of winning the next election, and vote share. I find that women incumbents are just as likely to run again in subsequent elections as men incumbents. However, women who lose an election appear to be more likely to quit politics compared to men who lose an election. I do not find clear incumbency effects for probability of winning at the next election and vote share.
