A couple of things about these polls:
1) They are registered voter and not likely voter right now. (Favoring Democrats)
2) For most of them, the assumption is that turnout will be close to 2012 levels, which is about D+5, which is how they likely grab their original registration data. (That may change when RV is converted to LV with these polls).
3) Clinton is enjoying a convention bounce, which will fade. She even just took a slight edge in the LA Times/USC poll this morning.
The left-wing press is doing the DNC’s bidding right now in an attempt to bury Trump. He will dig himself out of this hole and the horse race will be back on come Labor Day.
I hope you’re right. Just this morning a poll came out in Michigan and NH showing him down double digits. He was leading in both states a week ago.
