Correct me if I'm wrong but this is the same poll that had Trump leading most of 2016.
are you thinking of the LA Times tracking poll? I think MC had a slight Clinton lead most of 2016
I just looked at their 2016 last poll, should've been a warning sign for everyone - Clinton was only at 42% and 45% in both iterations
