You could say the same thing about ethnic candidates and ethnic voters who will vote for a candidate simply for being of the same background.
Being gay is a little different than having the same skin colour. Gays, in general, are more liberal and open-minded and less bigoted (although all those crazy gay Republicans in the States seem to suggest otherwise). But you know nfitz, if you didn't obfuscate and LIE and DECEIVE by cutting out parts of my post that didn't fit your argument you'd know Smitherman being gay wasn't my only reason for supporting him. But it's definitely a plus. And a city like Toronto deserves a gay mayor. Didn't Winnipeg already have one? WINNIPEG?
