Research on the political preferences of lesbian, gay and bisexual (LGB) voters shows that they are more progressive than heterosexuals. However, few studies consider differences between heterosexual, gay/lesbian, and bisexual men and women.

We offer an analysis of Canadian LGB voters' political preferences a decade and a half after same-sex marriage was legalized.

A more novel finding is that bisexual women are the most left-wing group. Lesbian women are only slightly to the left of heterosexual women. While left-wing bisexual women are growing in number, the overall gap between LGB and heterosexual voters has remained stable across generations, because marriage narrows some of the preference gaps.
