That's what I was suggesting. Since Rasmussen is restricted to land lines, they are missing a lot. Have they "corrected" for this now? Who knows?
Pretty much everyone was wrong in 2012 -- my guess is because Obamaphone users were under sampled. Gallup decided to give up presidential election polling after 2012, concluding that it's now impossible.
But whatever the true number is, Hillary is not ahead by 10%, either. Will Obamaphone users flock to the polls in 2016 for Hillary like they did in 2012 for Obama? Will half of the millennials living in mom's basement who voted for Bernie vote for Trump instead of for Hillary? We'll see.
