Take it with a grain of salt, but a family friend who is a top lobbyist for Boeing (among other companies) and extremely well-connected with Portman's office said that Portman thinks he'll lose and that the Portman camp's last internal had Strickland up by four points. They're planning to flood the airwaves, but don't think anything short of dead girl/live boy will tarnish Strickland's brand in Appalachia while the suburbs and cities will be brutal due to Trump and Presidential turnout respectively.
Well, great news
