Candidate gender quotas were passed into law in the Republic of Ireland in 2012. This paper examines support for this quota among three different groups: local election candidates, a sample of professionals and the general public. Using responses from three different datasets, we identify the key ideological, partisan and demographic predictors of support for the quota. We find the single best predictor of support for the quota is, not surprisingly, the gender of the respondent, followed by feminist ideology. There is a weak effect for left--wing ideology and partisanship and for beliefs regarding the causes of women's absence from political life. Overall, the results suggest that resistance to the quota is still relatively strong amongst both potential candidates for Dáil Éireann and the Irish electorate.
