He's the freaking mayor of Toronto, which has a very vibrant gay community, so if you decide you want to be mayor of Toronto you better get with the program. Gays are part of his constituency too.
On the other hand, looks like a lot of gay people, gay supporters, and young people (as always) stayed home last election day so maybe this will wake them up next time if they don't want a dolt like Ford in office. You get what you vote for (or don't vote for).
