George W. Bush won New Hampshire because of the Levinsky scandal, so Democrats should be careful about this. The real question is whether this backfires on Trump, in which case it could mean a yuge landslide loss (I could see NH voting like MA or MD in this case, for example). This is a very dangerous strategy with a 50/50 chance of being successful.
NH stuff aside, this is the primary way I could see Trump winning absent a 2008 style economic collapse. I think we are about to hear a lot about "Raping Bill."
He's trying to trigger one of those, too.
