Is there any precedent for a challenger winning when he's consistently down 7-10 points in polls in October? It's hard to imagine.
Heitkamp in 2012 I believe.
But yeah I think Beto is going to maybe do a little better than Hillary.
Not to be anal, but Heitkamp was only down 6. 
People are really exaggerating how much Heitkamp was down by in 2012. She was tied in the Atlas polling average on Election Day and never trailed in a non-Rasmussen poll within six months of the election by more than 2 points. She also led more polls than she trailed.
