You miss the point, the only point
The man is a queer. The only reason he is running is to increase queer viability. He is too seriously queer but not seriously presidential.
He in in effect a professional queer. He is queer for a living
Not so much. When he started attracting attention I don't think people knew he was gay.
He had the kind of resume that liberals like in candidates, but he wasn't going to go anywhere in Indiana politics, hence the presidential campaign.
Now he's attracting support because of the gay thing, but he'd be running even if he weren't homosexual.
