What is odd is the timing. I say this, even as I hope the Democrats win, and the story is very bad for the Republicans.
The problem is the very long history of using a "gay scandal" as a political tool, and even more particularly in the lead up to an election. For non-gays each scandal seems new, but for gay people with any life experience there is a depressing sameness about each episode.
