Trumps poll numbers have tanked nationally and in the key battlegrounds. It is still 3 months away from the election and convention bounce fades to kick in.
Nate Silver suggests that we should be wary of polls with such a lead now, if they still show it in 3 weeks then it will be far more predictive of the outcome.
Is there precedent for a bounceback to a competitive race? What would trump have to do to claw his way back to the polls?
