When a party selects an out lesbian as its leader, do women and LGBT people evaluate that leader more positively? And do they become more likely to vote for that party? We answer these questions using the case of Kathleen Wynne, premier of Ontario, Canada, from 2013 to 2018. We draw on four large-sample surveys conducted by Ipsos before and after the 2011 and 2014 Ontario elections. We compare shifts in best premier choice and vote choice among non-LGBT men, non-LGBT women, LGBT men, and LGBT women from 2011 to 2014. We find gender and LGBT affinity in leader evaluations. However, we find that only non-LGBT women and LGBT men were more likely to vote Liberal after Wynne became leader. This article contributes to research on affinity by examining LGBT affinity in a real-world election and the intersection of gender and LGBT affinity.
