Six, McFly?
It's called the "negative margin of victory manifesto." If Republicans get 55% while Democrats get just 45%, then the Democrats win the election by a margin of negative ten percentage-points.
Sorry, Rangel, but that only applies in the Senate--at least until your ugly partisans ratchet up the post-election legal campaign to impose your definition of victory upon us all. Heck, even I support a Democratic victory defined hence: Nancy Pelosi comes within twelve percentage-points of retaining her House seat, and no Democrat does better than she. That Republican blowout unfortunately still won't happen; we certainly need some reservation for the insane, and San Francisco clearly illustrates the culture of death, enslavement, and pursuit of misery at its finest.
